An unknown mixture was analyzed using TLC on a silica gel plateand developed in 1:6 ethyl acetate:hexane, and gave 2 spots with Rfvalues of 0.6 and 0.5 respectively. 1)Would this be considered agood separation between the two? Brieflyexplain. 2)Which spot represents the more polarcompound(s)? 3)Can you say for sure how many compounds arecontained in the mixture? If so, how many are there?Briefly explain. 4)If not, what furtherconditions might be performed to determine the number of componentsin the mixture or to obtain a better separation? Explain. 5)Supposeyou carry out a TLC separation of acetaminophen and aspirin onsilica gel using a nonpolar eluting solvent, hexane. Which shouldhave the larger Rf value? Brieflyexplain. 6)What are the methods for \"visualizing\"spots on TLC plates that we will use in this lab?
