Review of Oxidation and Reduction

Oxidation and reduction reactions, also known as redox reactions, involve the transfer of electrons from one substance that is being oxidized (losing electrons) to another that is being reduced (gaining electrons). A very common example of a redox reaction, one that you may very well have done in the lab, is the reaction that occurs when you place clean, iron nails into a copper sulfate solution. In this reaction, shown below, iron is oxidized and copper is reduced  

Two electrons are removed from iron by the copper ion. The iron, now an ion, moves into the solution, while copper, now a solid, forms on the surface of the nail. This process can be summarized using redox half-reactions (Chapter 10), such as the one shown here
