(D) The reaction between acidified potassium permanganate $(KMnO_4)$ and ferrous sulphate $(FeSO_4)$ is a classic redox reaction.In this reaction,$KMnO_4$ acts as a strong oxidising agent.It oxidises the ferrous ions $(Fe^{2+})$ present in the $FeSO_4$ solution to ferric ions $(Fe^{3+})$.During this process,the purple-coloured permanganate ions $(MnO_4^-)$ are reduced to colourless manganese ions $(Mn^{2+})$.As the concentration of $MnO_4^-$ decreases,the purple colour of the solution fades and eventually disappears.

Medium

$A$ 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 unstable compound and decomposes in presence of $FeSO_4$ to a colourless compound.
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 oxidising agent,it oxidises $FeSO_4$.
