The products obtained from a reaction of hydrogen peroxide and acidified potassium permanganate are :

Multiple Choice Options

  • A Mn4+,H2O\mathrm{Mn}^{4+}, \mathrm{H}_{2} \mathrm{O} only
  • B Mn2+,H2O\mathrm{Mn}^{2+}, \mathrm{H}_{2} \mathrm{O} only
  • C Mn4+,H2O,O2\mathrm{Mn}^{4+}, \mathrm{H}_{2} \mathrm{O}, \mathrm{O}_{2} only
  • D Mn2+,H2O,O2\mathrm{Mn}^{2+}, \mathrm{H}_{2} \mathrm{O}, \mathrm{O}_{2} only

Step-by-Step Verified Solution

2MnO4−+6H++5H2O2⟶2Mn2++8H2O+5O22 \mathrm{MnO}_{4}^{-}+6 \mathrm{H}^{+}+5 \mathrm{H}_{2} \mathrm{O}_{2} \longrightarrow 2 \mathrm{Mn}^{2+}+8 \mathrm{H}_{2} \mathrm{O}+5 \mathrm{O}_{2}

This reaction shows reducing action of H2O2\mathrm{H}_{2} \mathrm{O}_{2} in acidic medium.

The products formed are Mn2+,H2O\mathrm{Mn}^{2+}, \mathrm{H}_{2} \mathrm{O} and O2\mathrm{O}_{2}
