We chose these two solvent systems because they gave the best separation of the known compounds. Thus, we concluded that it would be easier and more straightforward to determine the unknown with these solvent systems. Our group’s unknown was Excedrin. We figured out the identity of our unknown analgesic because when we placed our TLC plates under the UV light, we observed three different spots for the unknown.
