A reaction in which one reactant undergoes oxidation whereas the other gets reduced during the course of reaction are termed as oxidation-reduction reactions or redox reactions. Oxidation refers to the loss of electrons or increase in oxidation state by a molecule, atom, or ion. Reduction refers to the gain of electrons or decrease in oxidation state by a molecule, atom, or ion.

Consider the following redox reaction.

Burning sugars, such as glucose (C₆H₁₂O₆) and the fatty acids in the fats we eat.

C₆H₁₂O₆(aq) + 6 O₂(g) --> 6 CO₂(g) + 6 H₂O(l)

Reaction of zinc oxide and carbon.

ZnO + C --> Zn + CO

In this reaction carbon is oxidised to CO and ZnO is reduced to Zn.
