Be able to rank solvents by polarity. • Know the criteria for selecting a recrystallization solvent. • Understand how recrystallization purifies a compound. • Understand the relationship between solubility and temperature. • Understand the relationship between solubility and IMFs. • Understand the relationship between melting point temperature and purity. • Calculate percent recovery (know formula). • Understand the purpose of each step involved in a vacuum filtration. • Identify what is happening in each filtration (e.g., what is in the filtrate and precipitate for each step). • Understand why each reagent was used in the order that it was in a recrystallization.
