C2H5OH (aq) + 4 KMnO4 (aq) → 4 MnO2 (s) + 4 KOH (aq) + 2 CO2 (g) + H2O (l)
This is an oxidation-reduction (redox) reaction:
4 MnVII + 12 e- → 4 MnIV (reduction)
2 C-II - 12 e- → 2 CIV (oxidation)
KMnO4 is an oxidizing agent, C2H5OH is a reducing agent.
This is a precipitation reaction: MnO2 is the formed precipitate.
This is a gas evolution reaction, CO2 is the formed gas.
- C2H5OH – Ethanol
- KMnO4 – Potassium manganate(VII)
- MnO2 – Manganese oxide , Manganese(IV) oxide
- KOH – Potassium hydroxide
- H2O – Water, oxidane
