- the process or result of oxidizing.
- the deposit that forms on the surface of a metal as it oxidizes.
- the act or process of oxidizing
- (as modifier)an oxidation state; an oxidation potential
1791, from French oxidation (1787), coined by G. de Morveau and A. Lavoisier, noun of action from oxider “oxidize,” from oxide (see oxide).
- The combination of a substance with oxygen.
- A reaction in which the atoms in an element lose electrons and the valence of the element is correspondingly increased.
- The chemical combination of a substance with oxygen.
- A chemical reaction in which an atom or ion loses electrons, thus undergoing an increase in valence. Removing an electron from an iron atom having a valence of +2 changes the valence to +3. Compare reduction.
Any chemical reaction in which a material gives up electrons, as when the material combines with oxygen. Burning is an example of rapid oxidation; rusting is an example of slow oxidation. (See combustion and reduction.)
