2Na + Cl2 2NaCl → This reaction involves gain & loss of electrons 2Na 2Na+ + 2e- (loss of electrons is oxidation) → Cl2 + 2e- 2Cl- ( gains of electrons is reduction) → An oxidation reduction reaction may also be defined as follows: Term Definition Oxidation Loss of electrons in a reaction. Reduction Gains of electrons in a reaction. Oxidizing factor The substance which gains electrons in a reaction. Reducing factor The substance which lost electrons in a reaction. Notes: The oxidizing agent is reduced in the reaction. The reducing agent is oxidized in the reaction. Oxidation & reduction are concurrent processes. (i.e. they occur together)
