Question

The oxidation state of $Mn$ in $K_{2}Mn{O}_4$ is same as that in $Mn{O}_2$.

Is the above statement true?

• A. True
• B. False

Answer 1

The correct option is B False

$K_{2}Mn{O}_4$= Oxidation number of $Mn$: $2+x+(-8)=0$

$\Rightarrow x=8-2$

$\Rightarrow x=+6$.

$Mn{O}_2$=Oxidation number of $Mn:x+(-4)=0$

$\Rightarrow x=+4$.
