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 `KMnO_(4)` and 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) rarr K_(2) SO_(4) + 2MNSO_(4)`
`[2FeSO_(4) + H_(2)SO_(4) rarr Fe_(2) (SO_(4))_(3) + 2H] xx 5`
`[2H + [O] rarr H_(2) O] xx 5`
`bar(2KMnO_(4) + 8H_(2) SO_(4) + 10 FeSO_(4) rarr)`
`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`.
