[ŏḱsĭ-dā́shən-rĭ-dŭḱshən]
(n.)A chemical reaction in which an atom or ion loses electrons to another atom or ion.

Oxidation-reduction reactions have many far-reaching applications in our lives. Some of these applications are so common, that we take them for granted; others are not so obvious. The following are just a few examples of oxidation-reduction reactions.

Redox - Wikipedia, the free encyclopedia
Redox (shorthand for reduction-oxidation reaction) describes all chemical reactions in which atoms have their oxidation number (oxidation state) changed. This can be either a simple redox process s...

Reduction potential - Wikipedia, the free encyclopedia
Reduction potential (also known as redox potential , oxidation / reduction potential or ORP ) is the tendency of a chemical species to acquire electrons and thereby be reduced. Each species has...

How do we know that the oxidation states have changed here? ... Oxidation reaction can be separated in space from the reduction reaction, if there is a way for the electrons and ions to be exchanged:

Half reactions are either an oxidation or a reduction. Only the species of atom that is involved in a change is in a half reaction. In the above reaction, silver goes from plus one to zero oxidation state, but to account for everything, the electrons must be placed into the half reaction.

Reduction and oxidation always occur together. If one thing is reduced, another thing is oxidized. The reactant that is reduced is called the oxidizing agent and accepts electrons. The reactant that is oxidized is called the reducing agent and supplies electrons.
