In this experiment, we will introduce the techniques of semi-microscale and microscale crystallization. We will also determine which solvent is most suitable for re-crystallizing an impure sample of fluorene. Lastly, we will determine the identity of an unknown using mixture melting point technique. • 0:44 Part A: Semimicroscale Crystallization - Erlenmeyer Flask and Hirsch Funnel • 10:11 Part B: Microscale Crystallization - Craig Tube • 18:15 Part C: Selecting a Solvent to Crystallize a Substance • 26:21 Part D: Mixture Melting Points
