DEFINITIONS OF OXIDATION AND REDUCTION (REDOX) This page looks at the various definitions of oxidation and reduction (redox) in terms of the transfer of oxygen‚ hydrogen and electrons. It also explains the terms oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side
