What happens when C2H5OH reacts with KMnO4

5 C2H5OH (aq) +2 KMnO4 (aq) +3 H.2SO4 (aq) → 5 CH3CHO (aq) +2 MnSO4 (aq) + K2SO4 (aq) +8 H.2O (l)

this is a Oxidation-reduction (Redox) reaction:

2 mnVII+10 e-→ 2 mnII(Reduction)

5 C-II-15 e-→ 5 CI.(Oxidation)

5 C-II+5 e-→ 5 C-III(Reduction)

KMnO4 is a Oxidizing agent, C.2H5OH is a Reducing agent, C.2H5OH is a Oxidizing agent.
