Why Dissolving and then reforming crystals can improve
their purity?
Answer Posted / obuli
The basic recrystallization plan is to dissolve an impure
solid in ahot solvent, then cool the solution so that the
desired molecules recrystallize while the
impurities remain in solution. Subsequent filtration
separates the solid crystal from the liquid
solvent.temperature (so that the impurities are freed), but
weak enough so that at least some of your
sample crystallizes out after cooling (so that you get at
least some yield harvested.)
