What is the chemical formula for potassium permanganate?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. KMnO4 .
The chemical formula for potassium permanganate is KMnO₄. It is a dark purple or almost black crystalline compound and is highly soluble in water, forming a bright pink or purple solution. Potassium permanganate is a strong oxidizing agent and is widely used in various applications such as water purification, disinfecting wounds, and in chemical titrations in laboratories. It contains potassium (K⁺) and the permanganate ion (MnO₄⁻), where manganese is in the +7 oxidation state. Due to its powerful oxidizing properties, KMnO₄ is also used in organic synthesis and in treating certain skin conditions in dilute form.
