Question

Equivalent mass of $KMn{O}_4$, when it is converted to $MnS{O}_4$, is:

• A. $M/5$
• B. $M/3$
• C. $M/6$
• D. $M/2$

Answer 1

The correct option is A $M/5$

The oxidation state of $Mn$ is changed from +7 to +2 when it is converted from $KMn{O}_4$ to $MnS{O}_4$
So the equivalent weight is $M/5$.
Hence option $A$ is correct
