Phosphoric acid (also known as orthophosphoric acid or phosphoric(V) acid) is a weak acid with 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, H₂PO⁻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, being building blocks for both DNA and RNA.
