Bromous acid is an acid with the formula HBrO2. It has bromine in the +3 oxidation state. The salts of bromous acid are called bromites. The acid is not stable and only occurs as an intermediate; for example, in the oxidation of hypobromites.
- HBrO + HClO → HBrO2 + HCl
- 2 HBrO → HBrO2 + HBr
Lastly, a synproportion reaction of bromic acid and hydrobromic acid gives bromous acid.
- 2 HBrO3 + HBr → 3 HBrO2
Several bromites are stable and have been isolated. For example NaBrO2· 3H2O and Ba(BrO2)2·H2O.
