Experiment 11: Synthesis of Aspirin pre-lab (4 pts) 1) (2 pts) Refer to the introduction on interpreting the ferric chloride test for phenols. Two students performed the aspirin synthesis experiment. Their melting point and ferric chloride test data are shown below. Based on the results, which student's aspirin has the higher purity? Justify your choice using the melting point data and ferric chloride test results. Melting point range for pure aspirin = 136-140 °C. Melting point range (°C) Ferric chloride...
