Identify correct statement for following reaction. $3 \mathrm{Br}_2+6 \mathrm{CO}_3{ }^{2-}+3 \mathrm{H}_2 \mathrm{O} \rightarrow 5 \mathrm{Br}^{-}+\mathrm{BrO}_3{ }^{-}+6 \mathrm{HCO}_3^{-}$
  1. Bromine is neither reduced nor oxidised
  2. Bromine is oxidised and carbonate is reduced
  3. Bromine is reduced and water is oxidised
  4. Bromine is both reduced and oxidised

Solution

$\mathrm{Br}_2$ is undergoing oxidation as well as reduction.
