24 H2(SO4) + 10 FeCl2 + 6 KMnO4 → 6 MnSO4 + 5 Fe2(SO4)3 + 3 K2SO4 + 10 Cl2 + 24 H2O

This is an oxidation-reduction (redox) reaction:

6 MnVII + 30 e- → 6 MnII (reduction)

20 Cl-I - 20 e- → 20 Cl0 (oxidation)

10 FeII - 10 e- → 10 FeIII (oxidation)

KMnO4 is an oxidizing agent, FeCl2 is a reducing agent, FeCl2 is a reducing agent.
