Determining the Empirical Formula of Copper Chloride Procedure 1. Put 25.0 mL of copper chloride in a buret, transfer to a 150mL beaker—the  reaction beaker. Record the mass. Thoroughly wash the graduated cylinder w/ water,  rinse thrice w/ 10mL of distilled water.  2. Get a piece of clean Zn, determine the mass. Record it. 3.  Pick up the piece of Zn w/ crucible tongs, tilt the reaction beaker at a 45- degree angle and slide the piece in w/o splashing the solution. 4. Stir the solution continuously w/ a clean plastic spoon or stirring rod, making  sure that the copper forming does not stick to the Zn.  5. Let the reaction continue until the blue color has disappeared, then add 5 to 10  drops of 10% HCl to the solution, and stir thoroughly. 6. W/ the crucible tongs, remove the Zn, put 10 mL of 10%HCl into a 150mL
