The catalyst used in preparation of oxygen from hydrogen peroxide is:
- A. manganese dioxide
- B. magnesium oxide
- C. manganese oxide
- D. manganese sulphate
Step-by-step solution
Manganese dioxide (MnO2) is a well-known catalyst for the decomposition of hydrogen peroxide into water and oxygen. The reaction is 2 H2O2 → 2 H2O + O2, and MnO2 speeds up the reaction without being consumed.
