A dilute ferrous sulphate solution was added to the beaker containing ...
In this reaction, potassium permanganate (KMnO4) is an oxidizing agent. It oxidises ferrous sulphate to ferric sulphate in the presence of dilute H2SO4.
2KMNO4 + 10FeSO4 + 8H2SO4 → K2SO4 + 2MnSO4 + 5Fe(SO4)3 + 8H2O
The solution is coloured purple because of the KMnO4 and it eventually disappears when all the KMnO4 in the solution is utilized.
2KMNO4 + 10FeSO4 + 8H2SO4 → K2SO4 + 2MnSO4 + 5Fe(SO4)3 + 8H2O

A dilute ferrous sulphate solution was added to the beaker containing ...
The correct explanation for the observation is option 'A': KMnO4 is an oxidising agent, it oxidises FeSO4.
Explanation:
When a dilute ferrous sulphate (FeSO4) solution is added to an acidified permanganate (KMnO4) solution, a redox reaction occurs. In this reaction, the permanganate ion (MnO4-) acts as the oxidizing agent, while the ferrous ion (Fe2+) acts as the reducing agent.
Here is the balanced chemical equation for the reaction:
5FeSO4 + 2KMnO4 + 8H2SO4 -> 5Fe2(SO4)3 + 2MnSO4 + K2SO4 + 8H2O
Explanation of the reaction:
1. KMnO4 is an oxidizing agent: Permanganate ion (MnO4-) is a strong oxidizing agent. It readily accepts electrons and gets reduced during the reaction.
2. FeSO4 is a reducing agent: Ferrous ion (Fe2+) is a reducing agent as it readily donates electrons and gets oxidized during the reaction.
3. Oxidation of FeSO4: In the reaction, FeSO4 gets oxidized to form ferric sulfate (Fe2(SO4)3). The Fe2+ ions lose electrons and are oxidized to Fe3+ ions.
4. Reduction of KMnO4: Permanganate ion (MnO4-) gets reduced to form manganese sulfate (MnSO4). The MnO4- ions gain electrons and are reduced to Mn2+ ions.
5. Change in color: The initial light purple color of the permanganate solution fades and finally disappears as the MnO4- ions are reduced to Mn2+ ions, which are colorless.
6. Formed products: The reaction also produces potassium sulfate (K2SO4) and water (H2O).
In conclusion, the correct explanation for the observation is that the KMnO4 is an oxidizing agent, and it oxidizes FeSO4 during the reaction. This results in the fading and disappearance of the light purple color of the permanganate solution.
