Answer to Question #154711 in Organic Chemistry for 123

Question

Balance the following reaction in a basic solution: I^- + MnO₄^2-- → MnO₂ + I₂

Answer 1

I^- + MnO₄^2- → MnO₂ + I₂ (basic solution)

2I^- - 2e^- → I₂ (oxidation)

MnO₄^2- + 2H₂O + 2e^- → MnO₂ + 4OH^- (reduction)

^{_______________________________________________________________}

2I^- - 2e^- + MnO₄^2- + 2H₂O + 2e^- → I₂ + MnO₂ + 4OH^-

2I^- + MnO₄^2- + 2H₂O → I₂ + MnO₂ + 4OH^-

Answer: 2I^- + MnO₄^2- + 2H₂O → I₂ + MnO₂ + 4OH^-
