Describe and explain the possible effect on your results of the following experimental errors or variations. in each case, specify the component(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 throughly. c) you mistakenly extracted the dichloromethane solution with 5% HCl rather than 5% NaHCO3. d) instead of using pH paper, you neutralized the NaHCO3 solution to pH 7 using litmus paper.
