Question

Give two examples of disproportionation reactions in aqueous solution.

Answer 1

1. \[\ce{\overset{0}{3Cl2} + 6OH- -> \overset{-1}{5Cl-} + \overset{+5}{ClO^-_3} + 3H2O}\]
2. \[\ce{\overset{+6}{MnO^2-_4} + 4H+ -> \overset{+7}{2MnO^-_4} + \overset{+4}{MnO2} + 2H2O}\]
3. \[\ce{2Cu+ -> Cu^{2+} + Cu}\]
