It is allowing chlorine to be reduced by supplying these two electrons. And chlorine, by undergoing reduction, is taking the electrons from the 2 sodium atoms. That allows sodium to be oxidized, so chlorine is the agent for the oxidation of sodium, or the oxidizing agent.

Oxidation and Reduction - Purdue University Magnesium therefore acts as a reducing agent in this reaction. The O 2 molecules, on the other hand, gain electrons from magnesium atoms and thereby oxidize the magnesium. Oxygen is therefore an oxidizing agent. Oxidizing and reducing agents therefore can be defined as follows. Oxidizing agents gain electrons. Reducing agents lose electrons. Assign an oxidation number to each element in the reaction. CO(g ... The oxidation state of each atom in the compound are; In CO - C has an oxidation number of +2; In H2 - H has an oxidation number of zero; In CH3OH - C has an oxidation number of-3, the oxidation number of O is -2 while the oxidation number of H is +1. Hence, the oxidation number of atoms in a compound are determined by some arbitrary rules.
