Answer to Question #144135 in Physical Chemistry for Shamen

Question

How to balance the following equation? Including steps

aC2H4 + bH2O +cH+ + 2MnO4- ---> dC2H6O2. + eMn2+

Answer 1

aC2H4 + bH2O +cH⁺ + 2MnO4^- ---> dC2H6O2. + eMn⁺²

MnO4^- + 5e^- + 8H⁺ = Mn⁺² + 4H2O - 2

C2H4 - 2e^- + 2H2O = C2H6O2 + 2 H⁺ - 5

2MnO4^- + 16H⁺ + 5C2H4 + 10H2O = 2Mn⁺² + 8H2O + 5C2H6O2 + 10H⁺

2MnO4^- + 6H⁺ + 5C2H4 + 2H2O = 2Mn⁺² + 5C2H6O2
