Explanation:

To balance the atoms other than H and O, coefficient 2 is added in front of CO

2

.

C is oxidized. Its oxidation number increases from +3 to +4. The net increase in the oxidation number is +2.

Mn is reduced. The oxidation number decreases from +7 to +2. The net decrease in the oxidation number is +5.

Hence, coefficient of C is multiplied with 5 and the coefficient of Mn is multiplied with 2.

To balance oxygen atoms, 7 water molecules are added to right. To balance H atoms, 15 protons are added to left.

Hence, the balanced reaction is

2MnO4−+5C 2 O42− +16H + →10CO 2+8H 2 O+2Mn 2+
