Question

The chemical reaction in which loss and gain of electrons takes place is called _______

Answer 1

Generally, oxidation and reduction occur in the same reaction. If one reactant gets oxidised, the other gets reduce. Such reactions are called oxidation-reduction reactions or redox reactions.

Example: $\mathrm{Zn}\left(\mathrm{s}\right)+{\mathrm{CuSO}}_4\left(\mathrm{s}\right)\to \mathrm{Cu}\left(\mathrm{s}\right)+{\mathrm{ZnSO}}_4\left(\mathrm{s}\right)$

Therefore, the chemical reaction in which the loss and gain of electrons take place is called the redox reaction.
