Equation 11. 3C + 2KMnO4 + 4H2SO4 -> 3CO2 + K2SO4 + 2MnSO4 + 4H2O

1. Detailed information about the equation 11. 3C + 2KMnO₄ + 4H₂SO₄ -> 3CO₂ + K₂SO₄ + 2MnSO₄ + 4H₂O

• This reaction is a redox reaction. In the reaction, KMnO₄ and H₂SO₄ react with C (Charcoal) to produce CO₂, K₂SO₄, MnSO₄, and H₂O.
• The initial chemicals: C (the main component of charcoal), KMnO₄ (potassium permanganate), H₂SO₄ (sulfuric acid).
• The products formed: CO₂ (carbon dioxide), K₂SO₄ (potassium sulfate), MnSO₄ (manganese sulfate), H₂O (water).

2. Reaction conditions

This reaction only takes place in the presence of high temperature and manganese (VI) oxide.

3. Reaction process

The reaction proceeds as follows:

• Charcoal is oxidized by KMnO₄ and H₂SO₄ to produce CO₂, K₂SO₄, MnSO₄, and H₂O.
• This process continues until there is no more charcoal.

4. Phenomena occurring

When the reaction occurs, CO₂ gas will appear (which can be detected by the phenomenon of gas rising). The color of the solution after the reaction will change due to the formation of K₂SO₄ and MnSO₄. If at high temperature conditions, boiling and evaporation phenomena can occur.
