Solution:

Electrolysis is the process by which a substance absorbs electricity and decomposes.

Electrolytes are substances that undergo chemical reactions during the passage of electricity, e.g. Sodium chloride, copper sulphate, silver nitrate. Acids, alkalis, and salts are electrolytes in molten and aqueous solutions.
The rods connected to the poles of the battery that transmit electricity to the electrolytes are called electrodes.

Electrochemical cells are systems that generate electricity through chemical reactions.

Electroplating – The process of using electricity to form a thin coating of other metals on a metal object.
