Question

Name the anode, the cathode and the electrolyte used in the electrolytic refining of impure copper.

Answer 1

Electrolytic refining is a process of refining a metal by the process of electrolysis. The main purpose of electrolytic refining is to purify the metals from the ores. With the use of electricity, the electrolysis technique is carried to purify impure Copper ($\mathrm{Cu}$).

Anode	Impure copper ($\mathrm{Cu}$)
Cathode	Pure copper ($\mathrm{Cu}$)
Electrolyte	Copper sulphate (${\mathrm{CuSO}}_4$) solution.
