THE SUBSTANCE WHICH GIVES OXYGEN FOR OXIDATION IS CALLED AN OXIDISING AGENT.
OR
THE SUBSTANCE WHICH REMOVES HYDROGEN IS ALSO CALLED AN OXIDISING AGENT.
EXAMPLE :- WHEN COPPER OXIDE IS HEATED WITH HYDROGEN , THEN COPPER METAL AND WATER ARE FORMED :
CuO+ H2 ------------ Cu + H2O
(1) IN THIS REACTION , CuO is changing into Cu. That is oxygen, is being removed from copper oxide. Now, By definition removal of oxygen from a substance is called reduction.
So we can say that copper oxide is being reduced to copper.
(2) In this reaction H2 is changing into H2O
That is oxygen is being added to hydrogen. Now , By definition addition of oxygen to a substance is called oxidation. So we can say that hydrogen is being oxides to water
