$\mathrm{H}_{2} \mathrm{O}_{2}$ acts as a reducing agent in :

A $\mathrm{Mn}^{2+}+2 \mathrm{H}_{2} \mathrm{O}_{2} \rightarrow \mathrm{MnO}_{2}+2 \mathrm{H}_{2} \mathrm{O}$
B $2 \mathrm{Fe}^{2+}+2 \mathrm{H}^{+}+\mathrm{H}_{2} \mathrm{O}_{2} \rightarrow 2 \mathrm{Fe}^{3+}+2 \mathrm{H}_{2} \mathrm{O}$
C $\mathrm{Na}_{2} \mathrm{S}+4 \mathrm{H}_{2} \mathrm{O}_{2} \rightarrow \mathrm{Na}_{2} \mathrm{SO}_{4}+4 \mathrm{H}_{2} \mathrm{O}$
D $2 \mathrm{NaOCl}+\mathrm{H}_{2} \mathrm{O}_{2} \rightarrow 2 \mathrm{NaCl}+\mathrm{H}_{2} \mathrm{O}+\mathrm{O}_{2}$

Accepted Answer

\mathrm{H}_{2} \mathrm{O}_{2}

act as a reducing agent.

2 \stackrel{+1}{\mathrm{Na}}\stackrel{-2}{\mathrm{O}} \stackrel{+1}{\mathrm{Cl}}+\mathrm{H}_{2} \mathrm{O}_{2} \longrightarrow 2 \mathrm{NaCl}+\mathrm{H}_{2} \mathrm{O}+\mathrm{O}_{2}

\mathrm{Cl}

from (+1) state changes to

\mathrm{Cl}^{-1}

.
