What is the change in the oxidation state of $\mathrm{Mn}$ in the reaction of $\mathrm{MnO}_4^{-}$with $\mathrm{H}_2 \mathrm{O}_2$ in acidic medium?
$7 ightarrow 4$
$6 ightarrow 4$
$7 ightarrow 2$
$6 ightarrow 2$
Solution
Manganese exhibits oxidation states of $+2,+3,+4,+6$ and +7 .
$\mathrm{So}$, in acidic medium on reaction of $\mathrm{MnO}_4^{-}$with $\mathrm{H}_2 \mathrm{O}_2$ it changes from 7 to 2 .
