Uses of Phosphoric Acid - ScienceStruck

Phosphoric acid, also known as orthophosphoric acid, is one of the most widely known and used acids. It is a mineral acid that contains three atoms of hydrogen, one atom of phosphorus, and four atoms of oxygen. Thus, the chemical formula of phosphoric acid is H 3 PO 4. This is an important acid which has a wide range of uses.
