Preparation of copper from copper(II) sulfate
Add 2.5 g zinc metal to the copper(II)sulfate solution ... and allow it to stand, stirring occasionally, until the solution becomes colorless. The complete disappearance of color can be verified by adding a small drop of this solution to 1 mL concentrated ammonia in a test tube. If the resulting solution is colorless, it is safe to assume that all the copper ion has reacted. (The copper ion produces a deep blue solution in an ammonia solution.) Copper metal and unreacted zinc metal are now present in the beaker.
Now you want to get rid of the zinc I assume?
Solublization of Excess Zinc Metal
After the blue color is gone add 8 mL dilute 6 M HCl to the beaker, and stir to dissolve the zinc. Warm the solution gently to speed up the reaction. Hydrogen gas is evolved in the reaction of zinc with the acid, and complete solution of the zinc is indicated when bubbles of hydrogen cease to be evolved. This reaction can be hastened by warming the solution. CAUTION! DO NOT HEAT TOO VIGOROUSLY.
Perhaps you want the copper clean?
Washing and Collecting Copper Metal
When the reaction of Zn and HCl has stopped, allow the copper precipitate to settle, and decant the supernatant into a beaker. Pour the decantant containing the zinc solution into the waste container provided. Wash the solid twice, using 50 mL portions of distilled water each time, decanting the wash water into another beaker after each washing. Be very careful not to lose any copper while decanting.
