In the reaction $3 Br_{2} + 6 CO_{3}^{2 -} + 3 H_{2} O \to 5 Br^{-} + BrO_{3}^{-} + 6 HCO_{3}^{-}$

Options:

Answer:

Solution:

$3 Br_{2} + 6 CO_{3}^{2 -} + 3 H_{2} O 5 Br^{-} \to + BrO_{3}^{-} + 6 HCO_{3}^{-}$ O.N. of $Br_{2}$ changes from 0 to -1 and +5 , hence it is reduced as well as oxidised.
