Purification Of Copper By Electrolysis

What is the process of purifying copper by electrolysis

2022-1-26  Copper is purified by electrolysis . Electricity is passed through solutions containing copper compounds, such as copper(II) sulfate. The anode (positive electrode ) is made from impure copper and the cathode (negative electrode) is made from pure copper. What is purification of a metal by electrolysis?
