Oxidation is a chemical reaction that involves the loss of electrons from a substance. It is a process in which a substance combines with oxygen or loses hydrogen atoms. Oxidation reactions often result in the formation of new compounds and the release of energy. This process is important in various fields such as chemistry, biology, and environmental science. Researchers study oxidation reactions to understand their mechanisms, kinetics, and applications in different industries. The study of oxidation also plays a crucial role in the development of technologies such as batteries, fuel cells, and combustion engines.
