OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
