Common but unique chemical compound which is always there in our day to day life!!! Sodium Bicarbonate...

Sodium Bicarbonate (NaHCO₃) is a white crystalline powder known to chemists as bicarbonate of soda, sodium acid carbonate or sodium hydrogen carbonate. Generic name of sodium bicarbonate is Backing Soda.

It is a salt made up of the cation sodium (Na⁺) and the anion bicarbonate (HCO₃). While it is a crystalline white solid, sodium bicarbonate often appears in the form of a fine powder. It tastes alkaline and somewhat salty, similar to that of washing soda (sodium carbonate). Nahcolite is a kind of natural mineral form. It may be found dispersed in a lot of mineral springs and is a part of the mineral natron.

Bicarbonate's prefix bi derives from an antiquated nomenclature that predates molecular understanding. It is based on the finding that sodium bicarbonate (NaHCO₃) contains twice as much carbonate (CO₃^-2) per sodium as does sodium carbonate (Na₂CO₃). The specific chemical compositions of these compounds, which were unknown when the name "bi-carbonate of potash" was first created, are now expressed in the contemporary chemical formulae for these compounds.

The substance sodium bicarbonate is an amphoteric one. Due to the production of carbonic acid and the hydroxide ion, aqueous solutions have a moderate alkaline pH.

 

Production

Industrial processes use sodium carbonate to make sodium bicarbonate.

Na₂CO₃ + CO₂ + H₂O → 2NaHCO₃

In a manner similar to that described above, soda ash, which is mined as the mineral trona, is dissolved in water and subjected to carbon dioxide treatment. From this solution, sodium bicarbonate crystallises as a solid.

Sodium bicarbonate is an intermediate in the reaction of sodium chloride, ammonia, and carbon dioxide in the Solvay process. Nonetheless, the product exhibits poor purity.

NaCl + CO₂ + NH₃ + H₂O → NaHCO₃ + NH₄C

Although of no practical value, NaHCO3 may be obtained by the reaction of carbon dioxide with an aqueous solution of sodium hydroxide.

CO₂ + NaOH → NaHCO₃

 

Application

Many applications include the use of sodium bicarbonate. It is used in a variety of industries, including those that produce food, animal feed, baking powder, fire extinguishers, sports supplements, agriculture, medicine, personal hygiene, odour control, hydrogen gas production, flue gas treatment, textile and leather industries, drilling, pest control, dyes, water treatment, plastic moulding, metallurgy, electronics, uranium mining, biogas, and more. It is also used as a cleaning agent, a mild disinfectant, to neutralise acids, and for pyrotechnics.

 

According to one survey, the following use percentages were found:

The most stable and effective antioxidant is a synthetic fat-soluble compound known as BUTYLATED HYDROXY TOLUENE (BHT) - E321.

The most stable and effective antioxidant is a synthetic fat-soluble compound known as butylated hydroxy toluene (BHT), which is chemically known as "2,6 Di Tertiary Butyl Para Cresol (DBPC)". It is also known as 2,6-di-tert-butyl-4-methylphenol, 3,5-di-tert-butyl-4-hydroxytoluene, and dibutylhydroxytoluene.

Chemically a phenol derivative, butylated hydroxytoluene (BHT) is an organic compound that is lipophilic and appears as white crystals or crystalline powder. It is insoluble in water but easily soluble in alcohol, acetone, toluene, and other hydrocarbon solvents.

Due to its antioxidant effects, it has been used as an ingredient in cosmeceuticals as well as culinary items. The reference number assigned to it is E321.

 

Manufacturing Process:

Sulfuric acid has been used to catalyse the reaction between p-cresol (4-methylphenol) and isobutylene (2-methylpropene), which results in the chemical synthesis of BHT:

CH₃(C₆H₄)OH + 2 CH₂=C(CH₃)₂ → ((CH₃)₃C)₂CH₃C₆H₂OH

Alternately, 2,6-di-tert-butylphenol has been used to make BHT by hydrogenolysis after hydroxymethylation or aminomethylation.

Uses:

• Butylated hydroxytoluene (BHT) is used in a wide range of goods, including cosmetics, rubber, electrical transformer oil, polymers, elastomers, lubricants, greases, edible oils, metalworking fluids, embalming fluid, food, animal feed, etc.
• BHT is a gasoline additive known as AO-29 in the petroleum sector and is used in jet fuel, turbine and gear oils, and hydraulic fluids.
• BHT's antiviral qualities make it ideal for usage in medicinal products.
• BHT is also used to stop the development of peroxide in various laboratory chemicals, solvents, and organic ethers.
• To ensure the safe preservation of certain monomers, it is used as a polymerization inhibitor.
• While some additive products use BHT as their main constituent, others only use it as one of many ingredients, frequently in combination with butylated hydroxyanisole (BHA).
• It prevents the production of peroxide in laboratory compounds like tetrahydrofuran, diethyl ether, and other chemicals by acting as a stabiliser.
• In the process of converting allyl alcohol to glycerine, it functions as a polymerization inhibitor. It is used to create the chemical methyl aluminium bis, an organoaluminum (2,6-di-tert-butyl-4-alkylphenoxide).
• BHT is often used to stop the oxidation caused by free radicals in fluids (such as fuels and oils) and other materials, and the U.S. F.D.A.'s regulations—which see BHT as "generally regarded as safe"—allow tiny quantities to be added to meals.
• Notwithstanding this and the National Cancer Institute's prior finding that BHT was not harmful in an animal model, social worries about its widespread usage have been voiced. BHT has also been proposed as a potential antiviral medicine, however as of December 2022, neither the scientific literature nor any drug regulatory bodies have authorised its usage as an antiviral.
• BHT's antiviral qualities make it ideal for usage in medicinal products.

Food Additives

• Due to its capacity to keep lipids from spoiling, BHT is largely utilised as an antioxidant food additive. Based on a 1979 National Cancer Institute research in rats and mice, it is categorised as generally regarded as safe (GRAS) in the United States. According to E321, it is legal in the European Union.
• Several foods include BHT as a preservation component. With this application, BHT preserves freshness or stops food from spoiling; it can also be used to slow down the pace at which food changes in terms of texture, colour, or flavour.
• BHT has been voluntarily removed from several food items or has been phased out by some food corporations.
• Its ideal concentration in packaged food goods is from 0.001%.

 Cosmetics

• It is also utilised in cosmetics since it aids in preventing the degradation of cosmetic items brought on by chemical interactions with oxygen.
• In cosmetics, the maximum concentration level is 0.5%.

Superior artificial antioxidant, Butylated Hydroxy Anisole (BHA)!

2-tertiary-butyl-4-hydroxy-anisole and 3-tertiary-butyl-4-hydroxy-anisole are two isomeric chemical compounds that are combined to form BHA, a waxy solid flake. Butylated Hydroxy Anisole (BHA) is the common name for this combination. It is a superior artificial antioxidant. It becomes a waxy solid that is white or yellowish at room temperature and has a light fragrant smell.

BHA's conjugated aromatic ring has the capacity to sequester free radicals by stabilizing them. Free radical scavengers inhibit more free radical reactions by doing so.

Butylated Hydroxy Anisole (BHA) is made from isobutylene and 4-methoxyphenol.

Application

Food:

In order to preserve food and food packaging, Butylated Hydroxy Anisole (BHA) is utilized. In order to stop or postpone oxidation, it is an efficient antioxidant employed in lipid, edible fats, and meals containing fat. Foods are preserved and their shelf lives are extended. By interacting with oxygen, it stops spoiling. By delaying the development of oxidation-related off flavors, odors, and color changes. Because of its antioxidant characteristics, BHA is added to meals that contain edible fats and prevents food from going rancid, which gives off unpleasant aromas. E320 is the number that has been given to it. It frequently pairs with butylated hydroxytoluene, a substance that is related to it (BHT). Around 85% of the 3-BHA and less than 15% of the 2-BHA in food-grade BHA.

Due to its excellent thermal stability and capacity to remain active in baked and fried meals, it is also employed in foods cooked or fried with animal oils (HSDB 2009). Ice cream, butter, lard, meats, cereals, baked goods, sweets, beer, vegetable oils, potato chips, snack foods, nuts and nut products, dried potatoes, and flavoring agents all include BHA. It is utilized in the production of sausage, poultry, and meat products, as well as dry mixes for drinks and sweets, glazed fruits, chewing gum, active dry yeast, beet sugar and yeast-based defoaming agents, and shortening emulsion stabilizers (IARC 1986). The petroleum wax coatings on food packaging are stabilized by BHA (HSDB 2009).

Prior to combining the dough or batter, BHA is often included with the lipid component of a baking formula for maximum efficacy. A BHA emulsion may occasionally be applied topically after the product has baked. BHA at a concentration of 0.02% can increase the shelf life of crackers and pastries by up to 33 days. In a similar vein, up to 0.02% of soda cracker biscuits contain BHA (based on lipid content). The incompatibility of BHA with ferric salts is one of its drawbacks.

Animal Feed:

Since it slows down the oxidation of lipids, vegetable oils, and vitamin A, BHA is one of the main antioxidants utilized in feeds. It works well as a stabilizer for polyethylene, paraffin, and essential oils (HSDB 2009). Animals are shielded against radiation as well as the acute toxicity of several xenobiotics and mutagens. Except for dogs with a maximum content of 150 mg/kg (FEEDAP) complete feeding stuffs (alone or together with BHT (E 321) and/or ethoxyquin (E 324)) and for dogs with a maximum content of 150 mg/kg complete feeding stuffs (alone or together with BHT (E 321)), BHA is intended to be used as an antioxidant in feeding stuffs for all animal species and categories. The BHA (Butylated Hydroxy Anisole) levels of antioxidant in finished feed are permitted to be 200 PPM by the U.S. Food and Drug Administration.

Pharma:

BHA is frequently found in medications including lovastatin, simvastatin, isotretinoin, and cholecalciferol (Vitamin D3).

Nutrition:

It can also be used for nutrition. BHA has the same anti-free radical properties as other antioxidants in biological tissues. Hence, it may help lower the risk of cardiovascular disease and other disorders. Concerns regarding BHA's possible side effects have surfaced recently, supporting consumer demands that all synthetic antioxidants be replaced with natural ones.

Cosmetics:

BHA is used in formulations for applying cosmetics that contain fats and oils. 90% of the BHA used in cosmetics is 3-BHA, while 8% is 2-BHA. According to one survey, recipes for lipstick and eye-shadow cosmetics used BHA the most frequently.

Other:

Tert-butyl hydroquinone has essentially taken the role of BHA in industrial applications. Moreover, rubber, petroleum-based goods, polymers, elastomers, lubricants, and greases employ Butylated Hydroxy Anisole (BHA).

One of the highly toxic component which is used in the synthesis of fumigants whose toxic vapours are used to poison and kill pests..... CHLOROACETONITRILE!!

The chemical name for Chloroacetonitrile is ClCH₂CN, which is also known as "cyanide chloromethane." It is colorless, fuming liquid with pungent choking smell. It is insoluble in water but soluble in ether, alcohol and hydrocarbons. It sinks in water because it is denser than water. It is highly toxic. Reacts with water and steam to produce toxic vapors of hydrogen chloride. When heated to decomposition, Chloroacetonitrile emits highly toxic fumes of hydrogen cyanide and hydrogen chloride.

Manufacturing process:

It can be obtained through the dehydration of chloroacetamide under the action of phosphorus pentoxide. Chloroacetamide [C₂H₄ClNO], trimethylbenzene [C₆H₃(CH₃)₃], and phosphorus pentoxide [P₄O₁₀] are examples of chemical compounds. For one hour, the liquid was slowly refluxed while being stirred ferociously. After that, it was allowed to cool to about 100 C° while being constantly stirred. Atmospheric pressure distillation was used to separate the crude product and some of the solvent. Phosphorus pentoxide (10 g) was added to the crude chloroacetonitrile to create a pure product before being redistilled via a productive packed fractionating column.

Other process is with the reaction between excess amount of acetonitrile [CH₃CN] with chlorine [Cl₂] at 460 ℃ as well as introducing ammonia gas [NH₃] into the ether solution of dichloro acetylene [C₂Cl₂].

 

Uses:

• Chloroacetonitrile can be used as a fumigant. Pesticides known as "fumigants" can be used to poison and kill pests using their volatile vapour. Its gaseous molecules have the ability to infiltrate the bodies of dangerous creatures and cause toxic consequences. It may also be found in forms other than gas, such as liquid, solid, or compressed gaseous form. The use dose can be determined using the area to be fumigated's volume (measured in g/m 3). The applied concentration can depend on the fumigation period, the proximity of the fumigation site, the volume of material, and its ability to absorb fumigant vapour. It can be utilised in places like a warehouse, tent, house, car, etc. that are closed off or almost closed off. It can successfully get rid of any concealed bugs or pathogens when there is a high concentration of the target object to be fumigated.
• It may be employed as an analytical reagent and as a raw material for organic synthesis.
• It is also applicable as a pharmaceutical intermediary.
• The electrochemical production of cyanoacetic acid with carbon dioxide uses chloroacetonitrile.
• It participates in the Darzen's condensation process with cyclohexanone that is phase-transfer catalysed.
• It is also employed in thermo-spray liquid chromatography/mass spectrometry as an eluent additive.
• it reacts with other reactants including malononitrile, aromatic aldehyde, and pyridine to create poly-substituted pyrido[1,2-a] benzimidazole.
• It is also used in Laboratory.

One of the purest and most concentrated forms of iron available on the market! Ferric Chloride...

Ferric chloride is the inorganic compound with the formula FeCl3. Also called Iron(III) chloride.  It is a common compound of iron in the +3-oxidation state. The anhydrous form is a crystalline solid. The colour varies on the viewing angle; crystals that reflect light seem dark green, while those that transmit light appear purple-red. It is highly soluble in methanol and diethyl ether. It is not flammable. It is corrosive to aluminium and most metals when wet.

Ferric Chloride is available in majorly three different forms. Anhydrous, Hexahydrate & Aqueous solution. Hexahydrate form is appearing as Brownish-yellow solid in the form of lumps. Its aqueous solution looks brown in color.

Iron(III) chloride is hazardous, very corrosive, and acidic. The anhydrous substance has a potent dehydrating effect.

Ferric chloride consumption can cause major illness and fatality, while instances of human poisoning are uncommon. Misdiagnosis or accident ingestion might result from improper labelling and storage. With people who have been poisoned severely, early diagnosis is crucial.

 

Manufacturing process for different form is as below, 

-        Anhydrous ferric chloride can be prepared by reaction of iron and chlorine.

2Fe_(s) + 3Cl_2(g) → 2FeCl_3(s)

-        Aqueous ferric chloride can be prepared by following three methods –

By dissolving iron ore in HCl

Fe₃O_4(s) + 8HCl_(aq) → FeCl_2(aq) + 2FeCl_3(aq) + 4H₂O_(l)

By oxidation of ferrous chloride with chlorine

2FeCl_2(aq) + Cl_2(g) → 2FeCl_3(aq)

By oxidation of ferrous chloride with oxygen

4FeCl_2(aq) + O₂ + 4HCl → 4FeCl_3(aq) + 2H₂O_(l)

Anhydrous ferric chloride cannot be produced by heating hydrated iron(III) chloride. Instead, the solid breaks down into iron oxychloride and hydrochloric acid. Thionyl chloride treatment can change hydrated iron(III) chloride into the anhydrous form. Similar to other chemicals, trimethylsilyl chloride can cause dehydration.

FeCl₃·6H₂O + 12(CH₃)₃SiCl → FeCl₃ + 6((CH₃)₃Si)₂O + 12HCl

Potassium Diformate!... The first animal nutrition growth-promoting product as a nonantibiotic.

Potassium Diformate is white or light-yellow crystal or crystal powder, it is easily soluble in water and highly hygroscopic. It is stable under acidic conditions, and easy to decompose into formic acid and potassium formate under neutral or slightly alkaline conditions. Potassium diformate is odorless, low-corrosive and easy to handle.

Potassium Diformate is also called as Formic Acid, Potassium Salt (2:1); Potassium Formate (1:2); Potassium Hydrogen Diformate (KHF).

Potassium hydrogen diformate is a kind of novel microbiotic growth promoter surrogate product of developing in recent years. Feeding test-results shows, adds the Potassium hydrogen diformate of 0.6%-1.2% in swine rations, can significantly improve the gaining effect of pig, reduces because the dead quantity that infectation of bacteria causes. Calendar year 2001 is used by European Union's approval, is first kind of non-antibiotic feedstuff additive product that is used for substituting the microbiotic growth promoter of European Union's approval, has an extensive future. Maximum inclusion level of potassium diformate is 1.8% as registered by the European authorities which can improve weight gain up to 14%.

Antibiotic growth promoters have been widely used in animal feed, with considerable success. Antimicrobial feed additives are widely used to improve the performance and ecology of animal production. Ban on antibiotics as growth promoters in the European Union, and the resulting pressures on meat exporters around the world have increased interest on alternatives like herbs, herbal products, prebiotics, probiotics organic acids (formic, fumaric, citric, lactic, propionic etc.). Organic acids and their salts have received much attention as alternatives to antibiotic growth promoters. These vary in the growth promoting effect and mode of action. Also, physical properties such as ease of handling, odor and corrosion during feed processing and on the farm should be taken into account when evaluating the different formulations. Numerous studies have demonstrated that formic acid is effective against pathogenic bacteria and enhancing growth performance but strong odor and corrosiveness limit its use. To overcome these problems, Potassium Diformate (PD) has received attention as an alternative to formic acid because of its easiness to handle and also effective in enhancing growth performance.

The European Union (EU) has approved it as non-antibiotic growth promoter, for use in non-ruminant feeds. Non-ruminant animals are animals with a single-compartment stomach, such as swine, poultry, horses, dogs, cats, and humans. Non-ruminant nutrition looks at the diet of these animals as it relates to their digestion, growth, performance, and overall health.

On this product, conclusions from the different researchers are as below,

-        We conclude from our research that our dietary potassium diformate can reduce mortality in Pacific white shrimp caused by the Gram-negative, pathogenic bacterium V. harveyi. It may be expected that similar outcomes may result with other Gram-negative bacterial pathogens in commercial shrimp farming operations. Considering our results on growth performance and survival rates, we believe that potassium diformate is a promising additive for economic and sustainable shrimp production, and should be considered in compound feeds for commercial, outdoor shrimp farming operations. - Dr. Christian Lückstädt; Orapint Jintasataporn, Kai-J. Kühlmann

-        The results indicate the promising potential of acidifiers in fish diets and provide evidence to encourage aquafeed manufacturers to consider using such additives. The dietary inclusion of Potassium Diformate (KDF) not only enhances the growth performance and the apparent protein digestibility of O. niloticus, but it also has an eubiotic effect on the proliferation of indigenous LAB, which plays a prominent role in activation of the immune response against diseases. - Nermeen M. Abu Elala, Naela M. Ragaa

Potassium Diformate increases performance

Stronger acid than nitric acid, sulfuric acid, and hydrochloric acid; It is Perchloric acid (HClO4) also called Hyperchloric acid or hydroxidotrioxidochlorine

With the chemical formula HClO₄, Perchloric acid is a chlorine oxoacid. It is a mineral acid also known as hydroxidotrioxidochlorine and hyperchloric acid. This colourless chemical, which is often found as an aqueous solution, is a stronger acid than sulfuric acid, nitric acid, and hydrochloric acid. When hot, it is a potent oxidant, although at room temperature, aqueous solutions up to about 70% by weight are often harmless, exhibiting only strong acid characteristics and no oxidising properties. Perchloric acid is one of the strongest Bronsted-Lowry acids as it functions as a super acid.

At room temperature, anhydrous perchloric acid is an oozy, unstable liquid. It produces at least five hydrates, several of which have undergone crystallographic characterization. These solids are made up of the perchlorate anion connected to H₂O and H₃O⁺ centers by hydrogen bonds. Perchlorate of hydronium is one instance. With water, perchloric acid forms an azeotrope that contains roughly 72.5% perchloric acid. This acid is readily available in the marketplace and is permanently stable. These substances are hygroscopic. As a result, concentrated perchloric acid dilutes itself when exposed to the air by absorbing water from the atmosphere. It corrodes both metals and tissue. Perchloric acid in closed containers that have been exposed to heat for a long time may violently burst.

The compound poses a fire and explosion risk since it is a strong oxidant and interacts violently with combustible and reducing substances, organic substances, and strong bases. It affects numerous metals, producing explosive/flammable gas. If the concentration is greater than 72%, the acid is unstable and may explode by shock or concussion when dry or drying. At normal temperature, mixtures containing flammable material, like paper, may spontaneously ignite. Never pour water directly into perchloric acid; instead, add the acid slowly to the water to dissolve or dilute.

Given that both substances are potent oxidizers, its risks resemble those of nitric acid in many ways. A further danger from perchloric acid is that its mist and vapour it can condense and form explosive metallic perchlorates in ventilation systems.

If a substance produces protons in an aqueous solution, it is referred to as an acid, and if its conjugate base is stable, it is referred to as a strong acid. Because of the negative charge conjugation that has formed on the oxygen atom and on all three other oxygen atoms in this instance, the perchlorate ion is stable.

A strong acid is one that readily releases hydrogen, hence the term. The readiness of the hydrogen atom to separate from the molecule depends on the central atom's oxidation number when it is in a different oxidation state than in the instances given above. The most common form of sulfuric acid is H₂SO₄ and sulphur has an oxidation number of +6. HClO₄ has a chlorine oxidation number of +7 while HClO₃ has a chlorine oxidation number of +5. As a result, perchloric acid's HClO₄ bond is the weakest, making it our choice for the strongest acid. Additionally, it is more potent than the most common nitric acid. Perchloric acid has a Cl oxidation state of +7 while sulphuric acid has a S oxidation state of +6. The O-H bond breaks more rapidly the more oxidised the core atom, making the acid stronger.

In contrast to other noncoordinating anion acids like hexafluorophosphoric acid and fluoroboric acid, which exhibit substantial susceptibility to hydrolysis, perchloric acid is weakly nucleophilic in nature and has little susceptibility to hydrolysis.

Caution:

Keep in mind that although being highly caustic by nature, perchloric acid is useful in rocketry due to the mixes it may create. We can also remark that since there are three oxygen atoms, they will pull oxygen hydrogen's electrons toward them, weakening the bond.

Process:

There are two methods for producing perchloric acid industrially. The high aqueous solubility of sodium perchlorate (209 g/100 mL of water at room temperature) is taken advantage of by the conventional approach. When such solutions are treated with hydrochloric acid, perchloric acid results, which precipitates solid sodium chloride

 NaClO₄ + HCl → NaCl + HClO₄

By distilling, the concentrated acid can be made pure. Anodic oxidation of aqueous chlorine at a platinum electrode is the more direct and salt-free alternative approach.

Acetic anhydride, which interacts with the water in perchloric acid to produce an anhydrous combination, is used to remove water from perchloric acid.

 

Uses:

• Ammonium perchlorate, a crucial component of rocket fuel, can be prepared with the help of perchloric acid, which is also useful for other perchlorate salts. Perchloric acid is very corrosive and easily creates mixes that could explode. As a result, perchloric acid is regarded as a crucial chemical in the space industry.
• In the process of separating sodium and potassium, perchloric acid is utilised as an oxidizer.
• Additionally, this substance is employed in the etching of liquid crystal display devices (often abbreviated to LCD). As a result, perchloric acid is also frequently utilised in the electronics sector.
• To separate potassium from sodium, as well as in other scientific experiments and commercial procedures, perchloric acid is utilised. As a result of its special characteristics, this substance is used in analytical chemistry.
• Used as a catalyst for the electropolishing or etching of molybdenum and chrome, as a reagent to determine the 1H-Benzotriazole, for plating metals, and in the manufacture of explosives.
• It is employed in the production of optical equipment, chemical products, fertiliser, and rust removal.
• In addition, perchloric acid is used in the extraction of materials from their ores in a number of significant ways.
• The perchloric acid salts are used in explosives and metal plating, among other things. Perchloric acid has the potential to detonate and releases toxic and corrosive vapours when heated.

Researchers should bear the following in mind while using or anticipating utilising perchloric acid in their experiments:

• Currently, there are no fume hoods on campus that can accommodate perchloric acid digestions in a secure manner. Due to the significant cost of cleaning these wash-down hoods of perchlorate pollution, any surviving hoods have been decommissioned and won't be turned back on.
• At no point should solvents be kept close to a designated perchloric acid location. These locations need to be marked with a sign that reads "Use Only Perchloric Acid. Organic Chemicals Are Not Allowed."
• Always add acid to water, not the other way around, using diluted perchloric acid (or any other acid).
• Researchers' tissues are just as susceptible to perchloric acid damage as sample tissue is. When handling perchloric acid, safety equipment such as goggles or face shields, gloves, and an apron are required.
• Until a perchloric acid digesting hood has been completely decontaminated, no work should be done in it due to the risk of an explosion.
• No garbage containing perchloric acid should be combined with any other waste. It should be placed in acid-resistant bottles (ideally the acid's original container), identified as hazardous chemical waste, and handled accordingly.
• Perchloric acid needs to be stored inside secondary containment, apart from all other compounds (such as a pyrex baking dish or plastic dish pan). It must not be kept next to bases, other organic or combustible materials, or organic acids like acetic acid.
