1. Water and toluene are very good recrystallization solvents. Why is it not useful to use these solvents for a ‘quick' recrystallization?
2. Acetone, dichloromethane, and diethyl ether are widely used organic solvents. Why is their use as a recrystallization solvent not always a good choice?
3. Why must we be careful how much solvent we use when performing a recrystallization?
4. Why would we use activated charcoal in the recrystallization process?
5. Why can't we use vacuum filtration when filtering solid impurities from a hot solution?
6. Why must we cool the heated solution slowly to room temperature before placing it in an ice bath instead of just placing it in an ice bath to begin with when we are recrystallizing our solute?
7. What are some ways to induce recrystallization (Name 3), if your solute refuses to recrystallize after performing the required 7 steps?
