Answer 1

ANSWER:-
Applications of Electrolysis

Electrolysis has wide applications in industries. Some of the important applications are, as follows, 
(i) Production of hydrogen by electrolysis of water.
(ii) Manufacture of heavy water 
(iii) The metals like K, Mg, Al, etc., are obtained by electrolysis of fused electrolytes.
(iv) Non-metals like hydrogen, fluorine, chlorine are obtained by electrolysis.
(v) In this method pure metal is deposited at cathode from a solution containing the metal ionsetc.
(vi) Compounds like NaOH, KOH, white lead, etc. are synthesised by electrosynthesis method.

(vii) Electroplating: The process of coating an inferior metal with a superior metal by electrolysis is known as electroplating.

The aim of electroplating is, to prevent the inferior metal from corrosion and to make it more attractive in appearance. The object to be plated is made the cathode of an electrolytic cell that contains a solution of ions of the metal to be deposited.
