. Coefficients of sulphuric acid and ferric sulphate in the balanced equation
KMnO4 + H2SO4 + FeSO4 K2SO4 + MnSO4 + Fe2(SO4)3 + H2O
Coefficients of sulphuric acid and ferric sulphate in the balanced equation of above reaction are respectively.
A: 8, 4
B: 5, 8
C: 4, 3
D: 8, 5
Best Answer
Correct Option is: (D)
8, 5
Explanation:
Manganese gains 5 electrons and the oxidation number changes from -7 to +2
Iron loses 1 electron and the oxidation number changes from +2 to +3.
Hence it is a redox reaction.
It can be balanced by the ion electron method.
Reduction half reaction
