Vedclass · Answer

(B) The equivalent weight of a substance is given by the formula: $	ext{Equivalent weight} = \frac{	ext{Molecular weight}}{	ext{n-factor}}$.For the equivalent weight to be half the molecular weight,the n-factor must be $2$.The n-factor represents the change in oxidation state of the central metal atom.In $MnSO_4$,the oxidation state of $Mn$ is $+2$.In $MnO_2$,the oxidation state of $Mn$ is $+4$.The change in oxidation state is $|4 - 2| = 2$.Thus,for the conversion $MnSO_4 	o MnO_2$,the n-factor is $2$,making the equivalent weight $\frac{M}{2}$.

The equivalent weight of $MnSO_4$ is half its molecular weight when it is converted to
