You will be using melting point to confirm the identity of the unknown drug in your drug mixture. If you did not have melting po
int data, could IR spectroscopy be used to differentiate among the three possible unknown drug compounds? Explain why or why not. In a separation experiment using an aqueous solution and dichloromethane, which layer is on the bottom of the separatory funnel-the aqueous layer or the dichloromethane layer? What physical property allows you to determine this without doing the experiment in lab? Describe an experimental procedure that you could use to test whether or not a particular layer in a separatory funnel is aqueous. Why is acetone used to rinse the original beaker and to wash the solid compound on the Buchner funnel? In Step 5 of the Procedure section below, why are you adding calcium sulfate to the solution in the Component B flask? Write out the flow chart on p.2. Using the information in the Introduction and Procedure sections of this lab, identify the Components A B, and C, and determine what compounds should be in the boxes with question marks. Note that the answer to this question is NOT a replacement for the Procedure section of your lab report.
