Question

describe the electrolytic refining of copper in brief​

Answer 1

Answer:

Copper(II) sulphate solution is the electrolyte. Copper dissolves at the anode: Cu → Cu2++2e, and is deposited at the cathode. The net result is transfer of pure copper from anode to cathode. Gold and silver in the impure copper form a so-called anode sludge at the bottom of the cell, which is recovered.

Answer 2

$\huge\purple{\mid{\fbox{\tt{αηsωєя࿐}}\mid}}$

Copper(II) sulphate solution is the electrolyte. Copper dissolves at the anode: Cu → ${Cu}^{2}$++2e, and is deposited at the cathode. The net result is transfer of pure copper from anode to cathode. Gold and silver in the impure copper form a so-called anode sludge at the bottom of the cell, which is recovered.❤
