Question

Oxidation reaction with its example ​

Answer 1

Oxidation is the loss of electrons or an increase in oxidation state by a molecule, atom, or ion.

ex:- Mg + O2 -------------> MgO

here magnesium is getting oxidized as it's oxidation state goes from 0 to +2

Reduction is the gain of electrons or a decrease in oxidation state by a molecule, atom, or ion.

ex:- Mg + O2 ----------> MgO

here oxygen is getting reduced it's oxidation state decreases from 0 to (-2)

That means oxidation and reduction both processes takes place simultaneously when a substance is getting oxidized then at the same time some other substance gets reduced

Answer 2

the reaction with the presence of oxygen is called oxidation
example the reaction of carbon and oxygen
to form carbon dioxide
