In an oxidation-reduction reaction, what happens to the electrons in the reduction process?

Answer : Gain of electrons.

Explanation : In a oxidation-reduction reaction often called as redox reactions, during the process of reduction the electrons are gained by the reduced species in the chemical reaction, whereas in the oxidation process the electrons are lost by the oxidised species. The total transfer of electrons forms the base of the redox reactions.

Redox chemical reactions are those where the oxidation states of atoms are changed.
