              • Prepare a saturated solution of the Cu2+ ion in concentrated HCl and note the green color of the solution due to the presence of the CuCl42- ion.
              • Pour 20 mL of the CuCl42- ion solution into 200 mL of water and note the formation of the light blue Cu(H2O)62+ complex.
              • Add 6 M NH3 drop by drop to a fresh solution of the Cu2+ ion until Cu(OH)2 precipitates.
              • Continue adding 6 M NH3 until the solution turns the deep blue color of the Cu(NH3)42+ ion.
