Answer to Question #288080 in General Chemistry for Preye
Question #288080
Balance the redox reactions in acidic solution.
1. KMnO4 + FeSO4 => MnSO4 + Fe2(SO4)3 + K2SO4
Expert's answer
MnO4− + 8H+ + 5e− = Mn2+ + 4H2O
Fe2+ − 1e− = Fe3+
MnO4− + 8H+ + 5Fe2+ = Mn2+ + 4H2O + 5Fe3+
2KMnO4 + 10FeSO4 + 8H2SO4 -> 2MnSO4 + 5Fe2(SO4)3 + K2SO4 + 8H2O
