Balance the following equation by oxidation reduction method FeSO4 +
KMnO4+ H2SO4 → Fe2 (SO4)3+ k2SO4+MnSO4+H2O

.

Explanation:

Identify the elements with oxidation state changes:

Oxidation states of iron, :

Oxidation state of manganese, :

The change in the oxidation state of is five times the opposite of the change to the oxidation state of . If there are one mole of atoms in each mole of this reaction, there would be five times as many atoms per mole reaction. In other words:

.

(Notice that each mole of this reaction would include five times as many atoms as atoms.)

Multiply the coefficients by to eliminate the fraction:

.

Find the unknown coefficients using the conservation of atoms.
