Some phosphorus oxoacids have two or more P atoms in different oxidation states. One example is Isohypophosphoric acid, H 4 P 2 O 6 (or H(OH)(O)P−O−P(O)(OH) 2), a tetraprotic acid and isomer of hypophosphoric acid, containing P in oxidation state +3 and +5; Phosphoric anhydride P 4 O 10 Some phosphoric acids
Pyrophosphoric acid. In chemistry, 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.
An oxyacid, oxoacid, or ternary acid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element , with at least one hydrogen atom bonded to oxygen that can dissociate to produce the H + cation and the anion of the acid.
Acid strength is the tendency of an acid, symbolised by the chemical formula, to dissociate into a proton, +, and an anion, . The dissociation or ionization of a strong acid in solution is effectively complete, except in its most concentrated solutions.
Phosphorous acid (or phosphonic acid) 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.

Hypophosphorous acid was first prepared in 1816 by the French chemist Pierre Louis Dulong (1785–1838). [4] The acid is prepared industrially via a two step process: Firstly, elemental white phosphorus reacts with alkali and alkaline earth hydroxides to give an aqueous solution of hypophosphites: P 4 + 4 OH − + 4 H 2 O → 4 H 2 PO − 2 + 2 H 2
Peroxydiphosphoric acid (H 4 P 2 O 8) is an oxyacid of phosphorus. Its salts are known as peroxydiphosphates. Its salts are known as peroxydiphosphates. It is one of two peroxyphosphoric acids, along with peroxymonophosphoric acid .
