(a) Are all pure liquids bad conductors of electricity ?
(b) Name a liquid which is a good conductor of electricity but does not undergo electrolysis on passing electric current.
(c ) If pure water is used, no electrolysis takes place. Why ?
(d) Name one practical application based on the phenomenon of electrolysis.

Explanation

(a) No, there are exceptions also. Mercury in pure state a good conductor of electricity.
(b) Mercury is a good conductor of electricity but does not undergo electrolysis.
(c ) Pure water `(H_(2)O)` does not dissociate into ions on passing electric current.
(d) The process of electroplating on the surface of metals is based on the phenomenon of electrolysis.
