Weigh your solid and determine a yield. To analyze your product, do each of the following: • Determine the mass of the crude (from Day 1) and of the re-crystallized product. These amounts will be your yield of both the crude and re-crystallized material. • Determine a percent yield (for crude and purified), based on theoretical yield (which reagent is limiting?). • Determine the melting point of both the crude and re-crystallized products (the literature value is 104-105 °C) • Do an IR spectrum (if requested by your instructor). Show the product to the instructor when you turn in your lab notebook for grading on the day you complete the experiment.
