An oxidator is a substance that promotes or facilitates the process of oxidation. Some of the synonyms for this term include oxidizing agent, oxidant, or oxidizer. These substances are often used in chemical reactions to promote the transfer of electrons from one molecule to another, resulting in a chemical reaction that changes the properties of the molecules involved. Other terms that are sometimes used interchangeably with oxidator include redox agent or redox catalyst, which refers to substances that are involved in both oxidation and reduction reactions. Regardless of the specific term used, oxidators play a crucial role in many important chemical processes in fields ranging from medicine to industrial production.
