CHEM 111LAB CHEMISTRY FOR ENGINEERSActivity 1Redox ReactionObjectiveTo determine relative oxidizing and reducing strengths of a series of metals and ionsIntroduction and Discussion of TheoriesOxidation-Reduction ReactionsAn oxidation-reduction (redox) reaction is a type of chemical reaction that involves atransfer of electrons between two species. An oxidation-reduction reaction is any chemicalreaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losingan electron. Redox reactions are common and vital to some of the basic functions of life,including photosynthesis, respiration, combustion, and corrosion or rusting.Redox reactions are comprised of two parts, a reduced half and an oxidized half, thatalwaysoccur together. The reduced half gains electrons and the oxidation number decreases,while the oxidized half loses electrons and the oxidation number increases. Simple ways toremember this include the mnemonic devicesOIL RIG,meaning "oxidation is loss
