Potassium permanganate is used to purify water as its is

The correct answer is oxidizing.

Key Points

• Potassium permanganate (KMnO₄) is a strong oxidizing agent that oxidizes dissolved impurities from water such as iron, manganese, and hydrogen sulfide (H₂S) by converting them into solid particles.
• These impurities are then filtered out of the water.
• It is a salt consisting of K⁺ and MnO^{− 4} ions.
• It is a strong oxidizing agent.
• It is used as a medication for cleaning wounds and dermatitis.
