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? [NCERT Exemplar]
A. KMnO4 is an oxidising agent, it oxidises FeSO4
B. FeSO4 acts as an oxidising agent and oxidises KMnO4
C. The colour disappears due to dilution, no reaction is involved
D. KMnO4 is an unstable compound and decomposes in the presence of FeSO4 to a colourless compound
