Synonym: oxyacid (oxy-acid)

Oxoacids (and its variants oxyacids, oxo acids, oxy-acids, oxiacids, oxacids) is a traditional name for any acid having oxygen in the acidic group. The term stands in contradistinction to `hydracids' (e.g. HCl) lacking oxygen. The term oxoacid now refers to a compound which contains oxygen, at least one other element, and at least one hydrogen bound to oxygen, and which produces a conjugate base by loss of positive hydrogen ion(s) (hydrons). E.g. P(OH)3 , RC(=O)OH , HOSOH , HOCl , HON=O , (HO)2SO2 , RP(=O)(OH)2 .
