WebA phosphite anion or phosphite in inorganic chemistry usually refers to [HPO 3] 2− but includes [H 2 PO 3] − ( [HPO 2 (OH)] − ). These anions are the conjugate bases of phosphorous acid (H 3 PO 3 ). The corresponding salts, e.g. sodium phosphite (Na 2 HPO 3) are reducing in character. Nomenclature [ edit] WebThe charge of the metal ion is determined from the formula of the compound and the charge of the anion. For example, consider binary ionic compounds of iron and chlorine. Iron typically exhibits a charge of either 2+ or 3+ (see [link] ), and the two corresponding compound formulas are FeCl 2 and FeCl 3 .

WebBranched polyphosphoric acids give similarly branched polyphosphate anions. The simplest example of this is triphosphono phosphate [OP(OPO 3) 3] 9− and its partially dissociated versions. The general formula for such (non-cyclic) polyphosphate anions, linear or branched, is [H n+2−k P n O 3n+1] k−, where the charge k may vary from 1 to n+2.
