Potassium permanganate is a chemical compound with the formula KMnO₄. It appears as dark purple or almost black crystals that dissolve in water to form a purple solution.
It is a strong oxidizing agent, meaning it can release oxygen and kill microbes, which makes it useful in medicine, water treatment, and laboratory work.
🧪 What is Potassium Permanganate used for?
🏥 1. Medical & First Aid Uses
- Treating infected wounds and ulcers
- Soaking skin infections like fungal infections
- Managing eczema and dermatitis (in very dilute form)
- Cleaning minor cuts to prevent infection
