- Detailed information about the chemical equation:
-
This equation describes the redox reaction between potassium permanganate (KMnO4) and concentrated sulfuric acid (H2SO4), producing potassium sulfate (K2SO4), manganese sulfate (MnSO4), water (H2O) and oxygen (O2).
-
According to the equation, 8 moles of potassium permanganate and 15 moles of concentrated sulfuric acid are required to produce 8 moles of potassium sulfate, 15 moles of manganese sulfate, 7 moles of water and 5 moles of oxygen.
- Reaction conditions:
This reaction requires high temperature and concentrated sulfuric acid to act as a catalyst.
- Reaction process:
- When heated, potassium permanganate reacts with concentrated sulfuric acid, reducing itself and oxidizing H2SO4 to SO2 and H2O.
- Potassium permanganate continues to reduce itself to MnSO4, during this process, oxygen is released.
- Observations:
- Potassium permanganate has a deep purple color, which gradually fades during the reaction and the light pink color of Mn2+ appears.
- When heated, oxygen gas is released.
- Potassium sulfate and manganese sulfate precipitate as a white solid.
