12 H2SO4 (aq) + 8 KMnO4 (aq) + 5 CH3COOH (aq) → 4 K2SO4 (aq) + 8 MnSO4 (aq) + 22 H2O (l) + 10 CO2 (g)

This is an oxidation-reduction (redox) reaction:

8 MnVII + 40 e- → 8 MnII (reduction)

5 CII - 10 e- → 5 CIV (oxidation)

5 C-II - 30 e- → 5 CIV (oxidation)

KMnO4 is an oxidizing agent, CH3COOH is a reducing agent, CH3COOH is a reducing agent.

This is a gas evolution reaction, CO2 is the formed gas.
