4 KMnO4 (aq) + 3 C2H5OH (aq) 4 MnO2 (s) + 4 KOH (aq) + 3 CH3COOH (aq) + H2O (l)

This is an oxidation-reduction (redox) reaction:

4 MnVII + 12 e- 4 MnIV (reduction)

3 C-II - 12 e- 3 CII (oxidation)

KMnO4 is an oxidizing agent, C2H5OH is a reducing agent.

This is a precipitation reaction: MnO2 is the formed precipitate.
