2. While caffeine is very soluble in water, aspirin is only minimally soluble. a. Clearly explain why you think caffeine is soluble in water. b. In order to dissolve the aspirin, I had to use a sodium hydroxide solution (this is why you had to add HCl to the separatory funnel.) Clearly explain how the use of a sodium hydroxide solution allowed the aspirin to dissolve. Structures/reaction(s) will likely help your answer.
