5 C6H12O6 (aq) + 24 KMnO4 (aq) + 36 H2SO4 (aq) → 24 MnSO4 (aq) + 12 K2SO4 (aq) + 30 CO2 (g) + 66 H2O (l)
This is an oxidation-reduction (redox) reaction:
24 MnVII + 120 e- → 24 MnII (reduction)
30 C0 - 120 e- → 30 CIV (oxidation)
KMnO4 is an oxidizing agent, C6H12O6 is a reducing agent.
This is a gas evolution reaction, CO2 is the formed gas.
