Question

Name the catalyst that is used in the preparation of the oxygen gas.

Answer 1

• Catalysts are those substances that alter the rate of a chemical reaction without actually taking part in it.
• The catalyst that is used in the preparation of oxygen gas is Manganese Dioxide (MnO₂).
• The chemical reaction for the same is given below
• $2{\mathrm{H}}_2{\mathrm{O}}_2\left(\mathrm{aq}\right)\stackrel{{\mathrm{MnO}}_2}{\to }2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{aq}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)$
