5 CH3OH (aq) + 6 KMnO4 (aq) + 9 H2SO4 (aq) → 3 K2SO4 (aq) + 6 MnSO4 (aq) + 19 H2O (l) + 5 CO2 (g)
This is an oxidation-reduction (redox) reaction:
6 MnVII + 30 e- → 6 MnII (reduction)
5 C-II - 30 e- → 5 CIV (oxidation)
KMnO4 is an oxidizing agent, CH3OH is a reducing agent.
This is a gas evolution reaction, CO2 is the formed gas.
