The oxidizing agent itself is reduced ... oxidation-reduction reaction, also called redox reaction, any chemical reaction in which the oxidation number of a participating chemical species changes. The term covers a large and diverse body of processes. Many oxidation-reduction reactions are as common and familiar as fire, the rusting and dissolution of metals, the browning of …

An oxidizing agent oxidizes another chemical and during the process lose electrons itself. These electrons are gained by the oxidizing agent, and so option 2 is part of our correct answer. Oxidization could also be an increase in the percentage of oxygen in a substance, which would require an oxidizing agent to donate oxygen. 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.
