Science glossary film: Redox reaction

A reaction in which oxidation and reduction occur together. For example, when iron oxide is heated with carbon, the iron oxide is reduced to pure iron, whilst the carbon is oxidised to form carbon dioxide. In the most general sense, oxidation involves the loss of electrons, and reduction involves the gain of electrons.
