Q. Statement 1: Equivalent mass of $KMnO _4$ is equal to one third of its molecular mass when it acts as an oxidising agent in an alkaline medium
Statement 2: Oxidation number of $Mn$ is $+7$ in $KMnO _4$

The d-and f-Block Elements

Solution:

In alkaline medium, $KMnO _4$ is reduced to $MnO _2$ which involves $3 e^{-}$
Thus, its eq. wt $=\frac{M}{3}$
