Anderson balancing redox equations by the oxidation. Determine the oxidation numbers of the species being oxidized and reduced and make sure there are the same number of atoms on each side. A reaction in which a reducing agent loses electrons while it is oxidized and the oxidizing agent gains electrons, while it is reduced, is called as redox oxidation reduction reaction. Balancing reaction equations oxidation state reduction. Even though the oxidation and reduction of a redox reaction take place simultaneously, each making the other possible, chemists often have reason to describe the reactions separately.
