Reading Experiment 11B in Pavia ( 5 th edition). Review all of the Techniques and material found in the Required Reading section for this experiment. Prelab Make an entry in your Laboratory notebook for this experiment. Include your Name , the Date , a Title for the experiment, and a brief Outline of the procedure that you will perform (see below). For this experiment, include the Chemical Equation for the reaction that you are performing (below). Also, you should make a Reagent Table to show the amounts of reagents that you plan to use (see the Laboratory Syllabus for an example). Note that you do not need an entry in the Reagent Table for the product, acetic acid. Determine which reagent is the limiting reagent and then calculate the Theoretical yield of the product, acetaminophen. All of the above should be done prior to setting foot in the laboratory! Procedure Follow the procedure in Pavia 5 th edition, Experiment 11B (Semi-microscale Procedure). (Remember, you should have a brief outline of this procedure in your prelab so that you should not have to read the textbook once you have entered the laboratory ). As you perform the experiment, it is important to record in your notebook the actual amounts of reagents that you use and the actual procedure that you perform, including any deviations from your outline or the textbook. Cover your final crystallized product and store it in your drawer to let it dry until the next week, then determine your product’s yield and melting point. To Complete the Experiment – Partial Report Weigh the dried, recrystallized product and calculate your percent yield. Turn in your final product in a labeled vial (see p. 5 98 in Pavia for what to put on the label - also add the date). Write a Conclusion about your results. Include in your conclusion the percent yield from your reaction and be sure to comment on the appearance and quality of your product. Answer the questions at the end of the experiment (1 through 6, p. 8 8 )
