Question

1. Thin Layer Chromatography a. (True/False) For a given sample, a single TLC spot is an absolute indication of sample purity. Explain. b. If a single solvent, such as ethanol (instead of a solvent mixture such as acetic acid/ethyl acetate) were used to elute the samples on the TLC plate, would you expect the Rf values to be greater or less than those you recorded? Explain your answer.
