NCERT · Class 11 · Chemistry · Redox ReactionsWhat is the oxidation number of Manganese (Mn) in Potassium Permanganate ($KMnO4$)?
Step-by-Step Solution
In $KMnO_4$, let the oxidation state of Mn be $x$.\nOxidation state of $K = +1$\nOxidation state of $O = -2$ $+1 + x + 4(-2) = 0 \implies 1 + x - 8 = 0 \implies x = +7$.
