- QUESTION 5 Following a reaction period of 150-minutes, you decide to perform an extraction to eliminate any triethylammonium chloride salts that formed as well as any potential remaining starting materials. You transfer the reaction mixture to a separatory funnel and add distilled water. Identify the layers in the separatory funnel. The top layer is the aqueous layer, and the bottom layer is the organic layer. The top layer is the organic layer, and the bottom layer is the aqueous layer. DCM and water are miscible solvents, and no layers form. Performing an extraction was a mistake. A distillation should have been used to purify the desired material. O Owhy ethyl acetate is immiscible with water?Now that you have learned about solubility, explain why aspirin crosses a cell membrane as a neutral carboxylic acid rather than an ionic conjugate base ?
