. Coefficients of sulphuric acid and ferric sulphate in the balanced equation


KMnO+ H2SO+ FeSO4 K2SO4 + MnSO+ 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.
