Boiling point elevation and freezing point depression
Boiling point elevation is the raising of a solvent's boiling point due to the addition of a solute. Similarly, freezing point depression is the lowering of a solvent's freezing point due to the addition of a solute. In fact, as the boiling point of a solvent increases, its freezing point decreases. An example of this would be the addition of ...

Freezing-point depression Definition and Formula
SOLVED: Consider the below three solvents and the corresponding values of Kf for each. Prove, using the formula for Kf, which one of these solvents would allow for the most sensitive procedure for determining the molar mass by the freezing point depression method. Explain well to receive any credit at all. [NOTE: An appropriate definition of "sensitivity" might be "giving the biggest detection signal (in this case, temperature change) for a small amount (molality) of unknown present."]Solvent
