Q. In which of the following compounds manganese has oxidation number equal to that of iodine in $KIO _{4} ?$

Redox Reactions

Solution:

Let oxidation number of $I$ in $KIO _{4}$ be $x$

$\therefore (+1)+x+4(-2)=0 \Rightarrow x=+7$

Let oxidation number of $Mn$ in $KMnO _{4}$ be $x^{\prime}$

$\therefore (+1)+x^{\prime}+4(-2)=0 \Rightarrow x^{\prime}=+7$
