- Boiling Point Elevation/Freezing Point Depression T = m K where, for freezing point depression: T = T(pure solvent) - T(solution) and for boiling point elevation: T = T(solution) - T(pure solvent) m = (# moles solute / Kg solvent) Kb = boiling point elevation constant. Kf = freezing point depression constant. Kb and Kf depend only on the SOLVENT. Below are some common values. Use these values for the calculations that follow.

- It is important to always minimize the amount of solvent used, allowing for evaporation. If we add a relatively large excess, we expect our recrystallization to produce lower percent recoveries. A common mistake is to misplace the decimal, resulting in addition of 11x the solvent instead of the recommended 1.1x. If a substance dissolves in a solvent at 1g/468 mL at room temperature and at 1g/13 mL at the solvent's boiling point, what would be the maximum expected amount recovered if using 11x the minimum amount of solvent in recrystallizing 10 g of the substance? Report your answer in grams to one decimal place.It is important to always minimize the amount of solvent used, allowing for evaporation.
