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 ions etc.
(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
