Answer 2

Given:

The given compound is potassium permanganate.

To find:

The oxidation number of Mn.

Solution:

The given compound is $KMnO_4$.

Let the oxidation number of Mn be x.

The charge of K is +1 and the charge of Oxygen is -2.

This compound has one K, one Mn and four oxygen atoms.

The compound is neutral so, the overall oxidation state is 0.

Thus we can write-

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

The oxidation number of Mn is +7.
