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.
In chemistry, phosphorus oxoacid (or phosphorus acid) is a generic name for any acid whose molecule consists of atoms of phosphorus, oxygen, and hydrogen. [1] There is a potentially infinite number of such compounds. Some of them are unstable and have not been isolated, but the derived anions and organic groups are present in stable salts and ...
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.
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.
They all have acidic protons bound to oxygen atoms, some have nonacidic protons that are bonded directly to phosphorus and some contain phosphorus–phosphorus bonds. [17] Although many oxoacids of phosphorus are formed, only nine are commercially important, and three of them, hypophosphorous acid , phosphorous acid , and phosphoric acid , are ...

Although acids such as phosphoric acid are written as H 3 PO 4, the protons are attached to oxygen atoms forming hydroxyl groups, so the formula can also be written as OP(OH) 3 to better reflect the structure. Sulfuric acid may be written as O 2 S(OH) 2; this is the molecule observed in the gas phase.
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:
