Question

Fill in the blanks:
i) Electrolysis involves a -------- and is a ---------reaction.
ii) Copper is a good -------- but is a --------.
iii) During the electrolysis of molten ionic chloride. -------- is obtained at cathode and ------- is obtained at anode.
iv) Weak electrolytes have ------- and ------ in their solutions.
v) --------- takes place at anode.

Answer 1

1) Electrolysis involves a chemical decomposition and is a redox reaction.
2) Copper is a good conductor of heat but it does not show reaction with water.
3) During the electrolysis of molten sodium chloride , sodium ion is obtained at cathode and chloride ion is obtained at anode.
4) Weak electrolytes have less dissociation and has small current.
5) Oxidation takes place at anode.
