Fill in the diagrams below to depict the extraction of a substance (e.g. caffeine, represented by black dots) from water into another solvent (in this case, DCM, the bottom layer) over three separate washes. I have completed the first extraction for you. Hint: think about concentration and the procedure - after the first wash, you will set aside the bottom (DCM) layer and the brown aqueous layer will remain in the separatory funnel. You will add fresh DCM to the funnel for the subsequent extractions. You do not need to count the dots, this is just an approximate picture.
