Which one of the following reactions indicates the reducing ability of hydrogen peroxide in basic medium?
Solution
$2 \mathrm{Mn}\overset{+7}{\mathrm{O}_{4}^{-}}+3 \mathrm{H}_{2} \mathrm{O}_{2} \rightarrow$
<br/><br/>
$2 \mathrm{Mn}\overset{+4}{\mathrm{O}_{2}}+3 \mathrm{O}_{2}+2 \mathrm{H}_{2} \mathrm{O}+2 \mathrm{O} \overline{\mathrm{H}}$
<br/><br/>
In basic medium $\mathrm{MnO}_{4}^{-}$is reduced to $\mathrm{MnO}_{2}$, whereas in acidic medium it is reduced to $\mathrm{Mn}^{+2}$.
