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.
