1. When doing a recrystallization, what observations would prompt you to perform a hot filtration?

2. What problems might arise if a hot solution is filtered by vaccum filtration?

3. What is meant when aniline is referred to as the "limiting reagent" in the reaction with acetic anhydried?

4. Under what circumstances would you use mixed solvents in a recrystallization?

5. Why do you we keep the volume of the rinses small in the recrystallization procedure?
