Phosphoric acid is a crystalline, colorless solid chemical. Phosphoric acid, composed of phosphorus, hydrogen and oxygen atoms, is represented by the chemical formula H3PO4. Phosphoric acid, which is used in industry, is obtained by heating calcium phosphate rock pieces with the help of sulfuric acid. The displacement of one or more of the hydrogen ions with the positive ions forms orthophosphate salts.
Phosphoric acid is a chemical that has a wide range of uses, addressing different sectors. Mostly used in phosphate fertilizer production, pesticide production, agriculture, cleaning of metals, polishing sector and food regulating acidity. Since microorganisms and fungi do not grow in acidic environments, phosphoric acid is also used for protective purposes.
