What is phosphoric acid

Phosphoric acid is often found in the form of a thick liquid. Many people commonly refer to this dense substance as orthophosphate, which is more ternary in nature. We mainly think of this substance as phosphorous - important oxygen - containing acid. It is important to note that phosphoric acid, even in liquid form, is highly corrosive and irritating to mucous membranes, eyes, and skin in laboratory animals and humans.

Phosphoric acid also contains salts, which have relatively low irritant potential. The dense acids do not contain carcinogenic or genotoxic substances, but they do have a reputation for promoting carcinogenic activities. Phosphoric acid has been an element of interest for a long time, and the world now widely recognizes this substance as a food additive.

5 Uses of phosphoric acid:

Step 1 Remove rust

Phosphoric acid is one of the common substances we use, among other acids, to remove rust from steel, iron and other metals. When phosphite comes into contact with rusty, brown-red metal, it produces something magical. Usually, the rust layer on the metal is iron oxide, which is converted by the action of phosphite into iron phosphate, a black compound. Once you have this black compound, you can simply wipe it off and the metal looks new again.

2. Multipurpose chemicals

Phosphite can also be used as a multipurpose chemical in a variety of agricultural, industrial and even many household products. For example, our various personal care products such as bath, cleansing, hair care, perfume, makeup, skin care and nail products contain phosphite. One of the main functions of this acid is to control pH.

3. Food additives

As we mentioned, phosphoric acid is now generally recognized around the world as a food additive. You'll find it in many foods, including cheese, processed meats, cereal bars, jams, cola drinks, and more. It acts as an acidity regulator in products and an acidifier in drinks. In addition, the main purpose of using this substance is to prevent the formation of bacteria and fungi in food and drink.

4. Medical use

The pharmaceutical industry uses phosphoric acid as an intermediate. You'll find it common during dental procedures, such as in etching solutions to clean teeth. In addition, many anti-nausea medications, mouthwash products, and tooth whiteners often contain phosphite.

5. Agricultural use

You can find several reports that conclude that phosphoric acid is present in nearly 8 percent of fertilizers commonly used in the agricultural industry. In addition, phosphoric acid is not only a popular ingredient in many of our favorite sodas, but also a flavoring and additive in poultry and animal foods.

When using phosphoric acid, the following precautions are recommended:

To protect the skin from phosphoric acid, we recommend wearing chemical protective clothing such as boots, protective clothing, and gloves. We also recommend that you purchase skin protective gear made of natural rubber, polyvinyl chloride, nitrile butadiene rubber, butyl rubber or neoprene rubber.

To protect the face or eyes from irritating and corrosive substances, we recommend the use of safety goggles for chemical protection.

In addition to general exhaust ventilation, we also recommend the use of local exhaust ventilation to prevent respiratory risks when using phosphoric acid. All necessary environmental precautions must be taken and direct outdoor emission of smoke may be required.
