Oxidation is a losing of electrons and Reduction is a gaining of electrons.

The reaction in which oxidation reduction taking place simultaneously are called as Redox reaction.

For example,

$cuo + h{ 2} = cu + h2o$

In this examples copper oxide is reduced and acts as oxidizing agent and H2

is oxidized and acts as reducing agent.these are the reaction in which oxidation and reduction are occurs in a same compound.

Plz try to understand the equation..
