Explain electrolytic refining of copper |
| Answer» Electrolytic\xa0refining of copper:In the process of electrolytic refining of copper, the electrolyte used is acidified copper sulphate.Impure metal is made as an anode and pure metal is made as a cathode.On passing the electric current through the electrolyte, the impure metal from anode dissolves into the electrolyte solution and pure metal from copper sulphate solution deposits on the cathode.At Anode: Cu\xa0→ Cu2+ + 2e-At Cathode:\xa0Cu2+ + 2e-\xa0→ CuThe soluble impurities go into the solution and insoluble impurities settle down at the bottom of an anode and are known as anode mud. | |
