Or you want a quick look:

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 Mn^VII + 30 e^- → 6 Mn^II (reduction) 20 Cl^-I - 20 e^- → 20 Cl (oxidation) 10 Fe^II - 10 e^- → 10 Fe^III (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.
