Phosphoric acid

Phosphoric acid, also known as orthophosphoric acid, has a chemical formula H3PO4 and a molecular weight of 97.9724. It is a common inorganic acid and is classified as a medium-strength acid. It can be obtained by dissolving phosphorus pentoxide in hot water. Industrial phosphoric acid is produced by treating phosphate rock with sulfuric acid. Phosphoric acid readily absorbs moisture from the air and can undergo dehydration when heated, resulting in pyrophosphoric acid and further dehydration to metaphosphoric acid. Phosphoric acid is primarily used in industries such as pharmaceuticals, food, and fertilizers, and can also be used as a chemical reagent.
