For the reaction: $I^{-} + C l O_{3}^{-} + H_{2} S O_{4} \to C l^{-} + H S O_{4}^{-} + I_{2}$

The correct statement(s) in the balanced equation is/are

(1) Stiochiometric coefficient of $H S O_{4}^{-}$ is 6

(2) Iodide is oxidized

(3) Oxidation number of chlorine changes by 5 units

(4) $H_{2} O$ is one of the products

Options:

Answer:

Solution:

Balanced chemical equation is

$\overset{- 1}{6 I^{-}} + C l O_{3}^{-} + 6 H_{2} S O_{4} \to C l^{-} + 6 H S O_{4}^{-} + \overset{0}{3 I_{2}} + 3 H_{2} O$

Hence statements 1, 2 and 4 are correct.
