Redox Reactions
Definition A redox reaction (reduction-oxidation reaction) is a chemical reaction in which electrons are transferred and the oxidation state changes. An example is the oxidation of elemental magnesium with oxygen: 2 Mg (elemental magnesium) + O2 (oxygen) 2 MgO (magnesium oxide). In this process, magnesium is called a reducing agent. It gives off two electrons. … Redox Reactions
