Oxidizing and Reducing Agents. An oxidizing agent, or oxidant, gains electrons and is reduced in a chemical reaction. Also known as the electron acceptor, the oxidizing agent is normally in one of its higher possible oxidation states because it will gain electrons and be reduced.A major form of toxicity arises from the ability of iron to redox cycle, that is, to accept an electron from a reducing compound and to pass it on to H 2 O 2 (the Fenton reaction). In order to do so, iron must be suitably complexed to avoid formation of Fe 2 O 3.The ligands determine the electrode potential; this information should be known before experiments are carried out.A redox mediator is a hyperbranched polymer having redox moieties (e.g. ferrocene) incorporated into its structure and/or chemically bonded to its periphery.
