Question

Quizplus · Accepted Answer

Potassium permanganate (KMnO4) is a well-known oxidizing agent and is a strong oxidizer in acidic medium. The presence of potassium and oxygen atoms, as well as high oxidation state of manganese (+7), in KMnO4 make it a strong oxidizing agent. Choice A (MnO) is a metal oxide, which can act as a reducing agent but not as an oxidizing agent. Choice B (MnSO4) and choice D (MnSO3) are metal sulfides, which are not commonly known as strong oxidizing agents. Choice E (MnSO4) is a metal sulfate, which is not commonly known as a strong oxidizing agent.
