GLOSSARY: Oxidiser

An Oxidiser, also referred to as an oxidizing agent, oxidant, or oxidiser can be defined as either a chemical compound that readily transfers oxygen atoms, or a substance that gains electrons in a redox chemical reaction. In both cases, the oxidizing agent becomes reduced in the process. Because the process of oxidation is so widespread (explosives, chemical synthesis, corrosion), the term oxidizing agent has acquired multiple meanings.
