10 FeCl2 + 6 KMnO4 + 24 H2SO4 → 5 Fe2(SO4)3 + 10 Cl2 + 6 MnSO4 + 3 K2SO4 + 24 H2O
This is an oxidation-reduction (redox) reaction:
[external_link offset=1]
6 MnVII + 30 e- → 6 MnII (reduction)
20 Cl-I - 20 e- → 20 Cl (oxidation)
10 FeII - 10 e- → 10 FeIII (oxidation)
KMnO4 is an oxidizing agent, FeCl2 is a reducing agent, FeCl2 is a reducing agent.
This is a precipitation reaction: Fe2(SO4)3 is the formed precipitate.
[external_link offset=2]
This is a gas evolution reaction, Cl2 is the formed gas.
