Describe briefly how you will purify it by using the chemical effect​

Answer 1

Answer:

In the purification of copper by electrolytic refining, the strip of impure copper metal is made the anode and a strip of pure copper metal is the cathode. A solution of copper sulphate is used as the electrolyte. When current is passed through the electrolyte, pure copper from the anode dissolves in the electrolyte

Answer 2

Answer:

Electrorefining

Explanation:

We will keep impure copper on anode and pure at cathode. The electrolytic sol of copper sulphate. We will get pure copper on anode after ectrolysis
