Oxidation is the addition of oxygen to a substance or removal of hydrogen, while reduction is the addition of hydrogen or removal of oxygen. An oxidizing agent provides oxygen for oxidation reactions and removes hydrogen, while a reducing agent provides hydrogen for reduction reactions and removes oxygen. Examples of oxidation-reduction reactions are provided along with identification of the oxidized substance, reduced substance, oxidizing agent, and reducing agent in each reaction.

2. Oxidation means the addition of
oxygen to a substance and the removal
of hydrogen from a substance is called
oxidation.

3. It means the addition of hydrogen to a
substance and the removal of oxygen to
a substance is called reduction.

4. It is reaction in
which both oxidation
and reduction take
place simultaneously.

5.  Cuo + H2 Cu + H2O
H2S + Cl2 S + 2HCl

6. The substance which gives oxygen for
oxidation and the substance which
remove the hydrogen is called
oxidising agents.

7. The substance which give
hydrogen for reduction and
the substance which remove
oxygen is called reducing
agents.
