1. What can you conclude if your dry aspirin sample has a lower melting point than the literature value? 2. If the yield of your dry aspirin is greater than 100%, what must you do experimentally to obtain a more reasonable yield? 3. Would the product isolated after Part A. 3 have a higher or lower melting point than that isolated after Part A. 5? 4. If the endpoint is surpassed in the analysis of the aspirin sample in Part B, will its percent purity be reported too high or too low? Explain.
