  Copper and Chlorine Gas Reaction | Cu + Cl2

  So we cannot prepare CuCl by this reaction directly. But we can reduce Cu 2+ ion to Cu + ion by a potassium iodide solution. When potassium iodide is added to copper chloride solution, iodide ion is oxidized to iodine. With that, copper +2 ion is reduced to copper +1 ion by forming CuCl. Cu + Cl 2 → CuCl 2 CuCl 2 + KI → CuCl + I 2 + KCl
