Step 3 of the procedure: What could you do if you wanted to extract the aspirin into the aqueous layer? Excedrin PM is a headache medicine taken at night that combines acetaminophen and diphenhydramine, an antihistamine with a basic amine that causes drowsiness. How would you extract an organic solution of diphenhydramine into an aqueous solution? CH2Cl2 Diphenhydramine 3. In step 1, why is CH2Cl2 used to dissolve the caffeine and aspirin but not the acetaminophen? Why is acetone required to do that (step 2)? Hint: Look at the Table from Lab 2. 4. Prepare a flowchart (similar to what you did for the last extraction lab) which has all of the solvents, reagents, and components for this lab, filled in by name. This flowchart should direct what actions you take at any point in this lab. (2 points)
