In this experiment you will observe a sequence of copper reactions. The sequence begins with copper metal and ends with copper metal, so it is called a cycle of copper reactions. Observations will be made for each reaction. Since no copper is added or removed between the initial and final reaction steps, copper can be quantitatively recovered.
