Your goal is to devise an experimental procedure that will allow you to quantitatively separate the components and determine their percent composition by mass in the mixture. Procedure: It’s up to you to determine the most efficient and economical methods that will achieve the objectives given in the problem. Consider using the common glassware, equipment, and chemicals that were utilized during your lab experiences in the Chem I class to decide what should be available. (You could check your Chem I lab notebook if you can’t remember!) Also, evaluate any chemical reagents you may wish to use based upon their availability, cost, and safe handling procedures. A free site where you can obtain this information is http://www.sciencestuff.com/msds/ Welcome Back! On the first day of school, you will be randomly assigned to a lab group. Be prepared to share your ideas and do some brain-storming to agree upon a plan of attack to solve this problem. You will then submit a group proposal, which I will evaluate based upon safety, available chemicals and equipment, and feasibility. Either your plan will be approved and experimentation may begin or your group may require further modifications before you may actually start the experiment. The Final Analysis: Upon completion of the experiment, you will submit a final report, summarizing your approved procedure, data, calculations, and conclusions. Your results will be compared to the known percent by mass composition of your mixture to determine the accuracy of your analysis. “Chance favors the prepared mind.” Louis Pasteur
