Experiment 10 - The extraction of Caffeine from Cola drinksProper Experimental TechniqueA liquid-liquid extraction is most easily performed with a separatory funnel. A separatory funnel is a vessel shaped like an ice cream cone, with a stopper on one end and a stem on the other end. The end with the stem has a stopcock to control the flow of liquid out of the funnel.
Carrying on with our example from the earlier section, here are the key steps for a successful extraction:
