A dilute ferrous sulphate solution was gradually added to the beaker containing acidified permanganate solution. The light purple colour of the solution fades and finally disappears. Which of the following is the correct explanation for the observation?

A

`KMnO_(4)` is an oxidising agent, it oxidises `FeSO_(4)`.

B

`FeSO_(4)` acts as an oxidising agent and oxidises `KMnO_(4)`.

C

The colour disappears due to dilution, no reaction is involved.

D

`KMnO_(4)` is an unstable compound and decomposes in presence of `FeSO_(4)` to a colourless compound.

Text Solution

Verified by Experts

The correct Answer is:
A
Acidified `KMnO_(4)` is an oxidising agent, it oxidises `FeSO_(4)`, hence pink colour of `KMnO_(4)`, fades and finally disappears.
`2KMnO_(4)+8H_(2)SO_(4)+10FeSO_(4)toK_(2)SO_(4)+5Fe_(2)(SO_(4))_(3)+2MnSO_(4)+8H_(2)O`
