Objective: The objective of this experiment is to separate the components in an Excedrin tablet. Reaction Equations: None Procedure: Non-aqueous bromine: Step 1: Place an Excedrin tablet in a 20mL beaker and add 8mL of dichloromethane. The pill should begin to dissolve. Step 2: Use a spatula to break up the pill until there are no large pieces. Step 3: Set up for vacuum filtration using a Hirsch funnel and a 25mL filter flask. Step 4: With the vacuum on, pour the solution through the Hirsch funnel/filter paper and into the filter flask. Step 5: Was any solid that is left in the beaker once with dichloromethane and pour it through the funnel as well. Step 6: Transfer the solid on the filter paper to another clean reaction tube. Step 7: Pour the liquid from the filter flask into a clean centrifuge tube, cap it, and set it aside. Step 8: To the solid from step 6, add 3mL of water and heat the mixture to boiling in a hot water bath. Step 9: After cleaning the filter flask, with acetone, vacuum-filter the hot mixture from step 8,
