(a) KMnO₄ is an oxidising agent, it oxidises FeSO₄

(b) FeSO₄ acts as an oxidising agent and oxidises KMnO₄

(d) KMnO₄ is an unstable compound and decomposes in the presence of FeSO₄ to a colourless compound.

The beaker containing the acidified permanganate solution was progressively filled with a diluted ferrous sulphate solution. The light purple colour of the solution fades and finally disappears. KMnO₄ is an oxidising agent, it oxidises FeSO₄ is the correct explanation for the observation.

Potassium permanganate (KMnO₄) serves as the oxidising agent in this reaction. In the presence of diluted H²SO₄, it converts ferrous sulphate to ferric sulphate.

2KMNO₄ + 10FeSO₄ + 8H₂SO₄ → K₂SO₄ + 2MnSO₄ + 5Fe(SO₄)₃ + 8H₂O

The KMnO₄ gives the solution its purple hue, which gradually vanishes once all of the KMnO₄has been used up.

Uses of Potassium Permanganate

As an antiseptic, KMnO₄ is frequently used to treat various fungal infections, ulcers, wounds, and other skin disorders.
It is mostly used in water treatment to eliminate minerals like iron and hydrogen sulphide as well as to manage organisms like zebra mussels.
The rust that may be present in water pipes and other equipment is also removed using this chemical compound.
The production of organic molecules is another significant application for potassium permanganate.
It assists in fruit preservation.
It can be discovered in survival kits. It is simple to use to ignite a fire.
It also functions as a rocket propellant.
Fish illnesses and parasites are treated with KMnO₄.

Summary:-

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?

The beaker containing the acidified permanganate solution was progressively filled with a diluted ferrous sulphate solution. The solution’s bright purple hue starts to wane and eventually vanishes. An oxidising agent, KMnO₄ oxidises The observation’s proper explanation is FeSO₄.
