WebThe oxygens will have a constant oxidation state of -2 which means only the chlorine is changing. It starts with +5 and proceeds to -1. A decrease in the oxidation number means a reduction. Next we separate the reaction into two half-reactions; an oxidation and reduction reaction. Oxidation: Br^ (-) → Br2 Reduction: ClO3^ (-) → Cl^ (-) WebMnO2 wouldn't be considered an oxyanion because it isn't an anion, it's a neutral compound.
