Question: Which of the following equation depicts the oxidizing nature of $\mathrm{H}_{2} \mathrm{O}_{2}$ ?
$\mathrm{KIO}_{4}+\mathrm{H}_{2} \mathrm{O}_{2} \rightarrow \mathrm{KIO}_{3}+\mathrm{H}_{2} \mathrm{O}+\mathrm{O}_{2}$
$2 \mathrm{I}^{-}+\mathrm{H}_{2} \mathrm{O}_{2}+2 \mathrm{H}^{+} \rightarrow \mathrm{I}_{2}+2 \mathrm{H}_{2} \mathrm{O}$
$\mathrm{I}_{2}+\mathrm{H}_{2} \mathrm{O}_{2}+2 \mathrm{OH}^{-} \rightarrow 2 \mathrm{I}^{-}+2 \mathrm{H}_{2} \mathrm{O}+\mathrm{O}_{2}$
$\mathrm{Cl}_{2}+\mathrm{H}_{2} \mathrm{O}_{2} \rightarrow 2 \mathrm{HCl}+\mathrm{O}_{2}$
Correct Option: , 2
Solution:
$\mathrm{I}^{-}$is oxidised to $\mathrm{I}_{2}$ by $\mathrm{H}_{2} \mathrm{O}_{2}$
Hence answer is (2)
