Reduction, oxidation, single replacement reaction, net ionic reaction, activity series. BACKGROUND The rusting of iron and the combustion of gasoline are common examples of oxidation–reduction reactions, often abbreviated redox reactions. Oxidation reactions are also thought to be partly responsible for the aging of the human body. This can depend on the specific lab where you get tested or how many tests you get done at once. If you order multiple tests, you may not get the complete results until all of the tests are completed. Sometimes a lab will only release results to your doctor, who reviews them and then releases them to...
