Mn3+ ions are unstable in solution and undergo disproportionation to give Mn2+, MnO2 and H+ ions. What will be the balanced equation for the reaction?
- 3Mn3+ + 4H2O → MnO2 + Mn2+ + 8H+
- Mn3+ + 4H2O → MnO2 + 4H+
- Mn + 2H2O → MnO2 + 4H+
- 2Mn3+ + 2H2O → MnO2 + Mn2+ + 4H+
Answer
(A) 3Mn 3+ + 4H 2 O → MnO 2 + Mn 2+ + 8H +
