WebJul 20, 2024 · Because phosphoric acid has three acidic protons, it also has three \(pK_a\) values. The \(pK_a\) values for any polyprotic acid always get progressively higher, … A phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus (P) atom is in the oxidation state +5, and is bonded to four oxygen (O) atoms, one of them through a double bond, arranged as the corners of a tetrahedron. Two or more of these PO 4 tetrahedra may be connected by shared single-bonded oxygens, forming linear or branched chains, cycles, or more co…
WebPhosphorous acid (or phosphonic acid (singular)) is the compound described by the formula H 3 PO 3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds.
