  • Phosphoric acid - Wikipedia

    Phosphoric acid (also known as orthophosphoric acid or phosphoric(V) acid) is a weak acid with the chemical formula H 3 P O 4. Orthophosphoric acid refers to phosphoric acid, which is the IUPAC name for this compound. The prefix ortho-is used to distinguish the acid from related phosphoric acids, called polyphosphoric acids.
