How can you use electrolysis to purify copper?
· Also asked, how does electrolysis purify copper? Electrolysis of copper transfers copper atoms from an impure copper anode to a pure copper hode, leaving the impurities behind. A thin sheet of highpurity Cu serves as the hode. The anode is the impure electrolyte is a solution of copper(II) sulfate.. One may also ask, what metals can be used for electrolysis?

In purifiion of copper, anode is
In electrorefining of copper, anode is impure copper or crude copper and hode is pure copper. Electrolyte: 15% C u S O 4 solution + 5% H 2 S O 4 When electric current is passed through the electrolyte, the anode gradually dissolves and pure copper is deposited on the hode, which gradually grows in size.
