When KMnO(4) reacts with acidified FeSO(...

When `KMnO_(4)` reacts with acidified `FeSO_(4)`

A

Only `FeSO_(4)` is oxidised

B

Only `KMnO_(4)` is oxidised

C

`FeSO_(4)` is oxidised and `KMnO_(4)` is reduced

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
`FeSO_(4)` is oxidised and `KMnO_(4)` is reduced.
`({:(2KMnO_(4) +3H_(2)SO_(4)toK_(2)SO_(4)+2MnSO_(4)),([2FeSO_(4)+ H_(2)SO_(4)toFe_(2)(SO_(4))_(3)+2H]xx5):})/(2KMnO_(4)+ 8H_(2)SO_(4)+10Fe SO_(4)to K_(2)SO_(4)+ 2MnSO_(4)+ 5Fe_(2) (SO_(4))_(3)+8H_(2)O)`
In this reaction oxidation state of Mn is changing from +7 to +2 while oxidation state of Fe is changing from +2 to +3.
