Bromic acid, HBrO3, is an oxoacid of bromine. It is a strong acid that is only known in aqueous solution.[2][3]
Preparation
Bromic acid may be prepared by
- reaction of sulfuric acid with a bromate (e.g., barium bromate);[3]
- electrolysis of a solution of bromine with platinum or lead dioxide anodes;[4]
- passage of a solution of an alkali bromate through a column of acid ion-exchange polymer.[5]
