oxidation

[‚äk·sə′dā·shən]
(chemistry)
A chemical reaction that increases the oxygen content of a compound.
A chemical reaction in which a compound or radical loses electrons, that is in which the positive valence is increased.

Oxidation

 

in the most limited sense, the combining of any substance with oxygen. Generally speaking, “oxidation” describes any chemical reaction that basically involves the removal of electrons from atoms or ions. The most important common oxidizing agents are oxygen (O2), ozone (O3), hydrogen peroxide (H2O2), chlorine (Cl2), fluorine (F2), potassium permanganate (KMnO4), perchloric acid (HClO4), and nitric acid (HNO3).

oxidation

Reaction of a chemical compound with oxygen, as in a paint film in which oil reacts with oxygen to form a hard dry film.
