How impure copper is purified by electrolysis? 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.
How does electrolysis work with copper? In copper electrolysis, when a current is applied, positively-charged copper ions (called cations) leave the anode (positive electrode) and move toward the cathode (negative electrode). … A dilute aqueous solution of copper sulfate and sulfuric acid is used as the electrolyte.
