1. (a) Describe any evidence that a chemical reaction occurred when you added 6 M HCl to the solution of sodium acetylsalicylate. (b) Explain why the changes that you observed took place. 2. Describe and explain the possible effect on your results of the follow ing experimental errors or variations. In cach case, specify the compo nent(s) whose percentage(s) would be too high or too low. (a) After adding dichloromethane to Panacetin, you didn't stir or shake the mixture long enough. (b) During the NaHCO3 extraction, you failed to mix the aqueous and organic layers thoroughly. (c) You mistakenly extracted the dichloromethane solution with 5% HCl rather than 5% NaHCO3. (d) Instead of using pH paper, you neutralized the NaHCO solution to pH 7 using litmus paper. 3. Although acetanilide and phenacetin aren't appreciably acidic, aceta minophen (like aspirin) is a stronger acid than water. What problem would you encounter if the unknown component were acetaminophen rather than acetanilide or phenacetin, and you extracted the aspirin with 5% NaOH
