WebbIn the S 4 O 62- ion, the total oxidation state of the sulfur atoms is +10. The average oxidation state of the sulfur atoms is therefore +2 1 / 2. STEP 3: Determine which atoms are oxidized and which are reduced. STEP 4: Divide the reaction into oxidation and reduction half-reactions and balance these half-reactions one at a time. The bromate anion, BrO 3, is a bromine-based oxoanion. A bromate is a chemical compound that contains this ion. Examples of bromates include sodium bromate, (NaBrO 3), and potassium bromate, (KBrO 3). Bromates are formed many different ways in municipal drinking water. The most common is the reaction of ozone and bromide:
