5 C2H5OH (aq) + 12 KMnO4 (aq) + 18 H2SO4 (aq) → 12 MnSO4 (aq) + 6 K2SO4 (aq) + 10 CO2 (g) + 33 H2O (l)
This is an oxidation-reduction (redox) reaction:
12 MnVII + 60 e- → 12 MnII (reduction)
10 C-II - 60 e- → 10 CIV (oxidation)
KMnO4 is an oxidizing agent, C2H5OH is a reducing agent.
This is a gas evolution reaction, CO2 is the formed gas.
