Solution Preview

In electrolytic refinement of copper, impurities from the recovered copper from ores are reduced. The copper with impurities is an anode in an electrolyte bath of sulfuric acid and copper (II) sulfate. The cathode used is a pure copper material. When current is passed through the circuit solution, the copper atoms on the ...
