Potassium permanganate is widely used in chemical industry and laboratories as a strong oxidizing agent, and also as a medication for dermatitis, for cleaning wounds, and general disinfection.

Is KMnO4 a reducing agent?

Its maximum oxidation state is +7 which it's already at. Therefore it can't oxidise so it can't act as a reducing agent.

Why is KMnO4 oxidizing agent?

Why? As the oxidation states of atoms increase the elements become more electronegative. Therefore, permanganate a good oxidizing agent.
