Phosphoric acid (also known as orthophosphoric acid or phosphoric(V) acid) is a mineral (inorganic) and weak acid having the chemical formula H3PO4. 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. Orthophosphoric acid is a non-toxic acid, which, when pure, is a solid at room temperature and pressure. The conjugate base of phosphoric acid is the dihydrogen phosphate ion, H
4, which in turn has a conjugate base of hydrogen phosphate, HPO2?
4, which has a conjugate base of phosphate, PO3?
4. Phosphates are essential for life.
Fertilizers are the dominant use of phosphoric acid. Other far smaller but still significant uses include food additive, cleaning products, and water treatment.
The most common source of phosphoric acid is an 85% aqueous solution; such solutions are colourless, odourless, and non-volatile. The 85% solution is a syrupy liquid, but still pourable. Although phosphoric acid does not meet the strict definition of a strong acid, the 85% solution is acidic enough to be corrosive. Because of the high percentage of phosphoric acid in this reagent, at least some of the orthophosphoric acid is condensed into polyphosphoric acids; for the sake of labeling and simplicity, the 85% represents H3PO4 as if it were all in the ortho form. Dilute aqueous solutions of phosphoric acid exist in the ortho form.
