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
.
