(A) HOCl + H_2 O_2 → H_3 O^++ Cl^-+ O_2 (B) I_2+ H_2 O_2+2 OH^- → 2 I^-+2 H_2 O + O_2 Choose the correct option.
(A)
$\displaystyle \mathrm{HOCl}+\mathrm{H}_2 \mathrm{O}_2 \rightarrow \mathrm{H}_3 \mathrm{O}^{+}+\mathrm{Cl}^{-}+\mathrm{O}_2$
(B)
$\displaystyle \mathrm{I}_2+\mathrm{H}_2 \mathrm{O}_2+2 \mathrm{OH}^{-} \rightarrow 2 \mathrm{I}^{-}+2 \mathrm{H}_2 \mathrm{O}+\mathrm{O}_2$
Choose the correct option.
Official answer
(2)
$\displaystyle \mathrm{H}_2 \mathrm{O}_2$ acts as reducing agent in equations (A) and (B).
