Post-Lab Questions: 1. What is an emulsion and what are some methods to help break them up if they form between two immiscible layers? 2. Is ethyl acetate a suitable solvent for extraction of caffeine? Hint: Discuss the miscibility of this organic layer with an aqueous layer. How about acetone? 6. If you used ethyl acetate in place of methylene chloride which would be the top layer in an extraction with water? Why?
