In the extraction of copper from an ore by electrolysis, pure copper is used for the cathode and the ore is used as the anode, both in copper (II) solution. Copper from the ore dissolves then plates onto the cathode. some impurities from the ore dissolve in the solution while others remain solid and fall to the bottom as anode sludge.
Which of these metals could be in the anode sludge? check all that apply
