Barium bromate is a chemical compound composed of the barium ion and the bromate ion, with the chemical formula of Ba(BrO₃)₂.

Preparation

Barium bromate monohydrate can be prepared by reacting potassium bromate or sodium bromate with barium chloride:^[4]

2 KBrO₃ + BaCl₂·2H₂O → Ba(BrO₃)₂·H₂O + 2 KCl + H₂O
