Choose the correct option.


(A) $\mathrm{HOCl}+\mathrm{H}_{2} \mathrm{O}_{2} \rightarrow \mathrm{H}_{3} \mathrm{O}^{+}+\mathrm{Cl}^{-}+\mathrm{O}_{2}$

(B) $\mathrm{I}_{2}+\mathrm{H}_{2} \mathrm{O}_{2}+2 \mathrm{OH}^{-} \rightarrow 2 \mathrm{I}^{-}+2 \mathrm{H}_{2} \mathrm{O}+\mathrm{O}_{2}$

Choose the correct option.


  1. $\mathrm{H}_{2} \mathrm{O}_{2}$ act as oxidizing and reducing agent respectively in equations (A) and (B).

  2. $\mathrm{H}_{2} \mathrm{O}_{2}$ acts as oxidizing agent in equations (A) and (B).

  3. $\mathrm{H}_{2} \mathrm{O}_{2}$ acts as reducing agent in equations (A) and (B).

  4. $\mathrm{H}_{2} \mathrm{O}_{2}$ acts as reducing and oxidising agent respectively in equation (A) and (B).

Correct Option: , 3


When $\mathrm{H}_{2} \mathrm{O}_{2}$ acts a reducing agent it liberates the $\mathrm{O}_{2}$.

$\mathrm{H}_{2} \mathrm{O}_{2} \rightleftharpoons 2 \mathrm{H}^{+}+\mathrm{O}_{2}+2 \mathrm{e}^{-}$
