Sam Christy Lab Partners: Jarrod Googins, Travis Dunn TA: He Li 12/08/07 The Copper Cycle Introduction: This lab demonstrates how chemists often integrate a series of chemical reactions, or “steps,” together to produce a desired product. Each one of the steps is crucial to completing the cycle. For this lab we used copper to follow the copper cycle. We started with copper turnings, transformed them into many different forms, and then transformed it back into copper. Procedure: To complete the first reaction of the cycle, take 1g of copper wire and place it into a 125 mL flask. Then, under the hood, add a two-fold excess of 16 M concentrated nitric acid slowly into the flask. Then let the copper wire dissolve completely in the flask. When the reaction slows, place it on the Bunsen burner to speed the reaction up. Let cool. To complete the second reaction, transfer the solution into a 250 mL beaker. Add 30 mL of 6 M sodium hydroxide to the beaker. Test the acidity of the solution with litmus paper. If the paper turns blue, then proceed to the next step.
