macroscale (1.00 g solid)

The scenario is: you have an organic solution containing your assigned compound of interest, as well as organic soluble impurities. You want to isolate the crude solid compound of interest away from these impurities. Then, you want to recrystallize this material.

Write answers to the following questions, and then upload them as a PDF:

1. What aqueous solution would you use to extract your desired compound out of the organic solution? (the exact concentration does not matter for this exercise).
2. What would you add to the aqueous extract to precipitate your desired compound? Around what pH would you expect the precipitation to be essentially complete?
3. The solubilities of your compound in boiling ethanol and in 20 C ethanol are included in the Google Doc chart. Using them:
   • Determine the expected volume of ethanol that will be required to dissolve your compound.
   • Determine the maximum amount of recrystallized compound that could be isolated from the mother liquor (the first crop of crystals only).
4. From the expected volume of solvent required for the recrystallization, describe what equipment and glassware you would require to perform the recrystallization (just the recrystallizationdon't worry about filtration, extraction, etc.)
