Mn 3+ and Co 3+ ions are the strongest oxidising agents in

WebNow Mn3+ is a strong oxidising agent. A good oxidizing agent reduces itself . i.e. gains electrons from other. Its tends to gain one more electron to acquire stable electronic … WebThe permanganate ion removes electrons from oxalic acid molecules and thereby oxidizes the oxalic acid. Thus, the MnO 4-ion acts as an oxidizing agent in this reaction. Oxalic acid, on the other hand, is a reducing agent in this reaction. By giving up electrons, it reduces the MnO 4-ion to Mn 2+.. Atoms, ions, and molecules that have an unusually large affinity for … brandon herman
