Oxidation Definition


Definition: Oxidation is the loss of electrons during a reaction by a molecule, atom or ion.

Oxidation occurs when the oxidation state of a molecule, atom or ion is increased.

An older meaning of oxidation was when oxygen was added to a compound. Example: Iron combines with oxygen to form iron oxide or rust. The iron is said to have oxidized into rust.
