Question

define electrolytic refining of copper?give the chemical reaction.Draw a lablled diagram​

Answer 1

Answer:

In the electrolytic refining of copper, the impure metal is made the anode and a thin strip of pure metal is made the cathode, a solution of the metal salt is used as an electrolyte. on passing the current through the electrolyte,the pure metal from the anode dissolves into the electrolyte

Answer 2

Answer:

The purification of metals by electrolysis. It is commonly applied to copper. A large piece of impure copper is used as the anode with a thin strip of pure copper as the cathode. ... Gold and silver in the impure copper form a so-called anode sludge at the bottom of the cell, which is recovered.

chemical reaction; Cu → Cu2++2e
