keep impure copper at anode and purecopper wire at cathode
At anode
Cu --------------Cu²+ + 2e-
At cathode
Cu²+ + 2e- ------------- Cu
* Salt solution of copper (CuSo4 ) is used as the electrolyte.
* The copper from the anode goes to the solution as C
* Cu²+ ion goes to the cathode and gets deposited.
Uses Of Copper:
1- Electrical wiring: good conductor of electricity.
2- Domestic plumbing: does not react with water.
3- Making alloys like brass (zinc & copper): harder than copper & zinc.
4- Making coins: long lasting without any corrosion.
