Vedclass · Answer

(B) The chemical formula for potassium permanganate is $KMnO_4$. Oxidation number of $K = +1$. Oxidation number of $O = -2$. Since $KMnO_4$ is a neutral molecule,the sum of the oxidation numbers of all atoms must be $0$. Let the oxidation number of $Mn$ be $x$. $(+1) + x + 4 	imes (-2) = 0$. $1 + x - 8 = 0$. $x - 7 = 0$. $	herefore x = +7$. Thus,the oxidation state of manganese in $KMnO_4$ is $+7$.
