Oxidizing and Reducing Agents

The 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 electrons tend to be good ...
