colligative properties freezing point depression
Why is freezing point depression colligative?
Freezing point depression is colligative for most solutes since very few solutes dissolve appreciably in solid solvents. The boiling point of a liquid at a given external pressure is the temperature ( ) at which the vapor pressure of the liquid equals the external pressure.
How do you find the freezing-point depression constant?
This applies also to freezing-point depression. Likewise, for practical applications, we usually find the freezing-point depression constant by measuring the depression of the freezing point of a solution of known composition.
What is the temperature difference between boiling point elevation and freezing-point depression?
The temperature difference is the freezing-point depression. In the boiling-point elevation case, we assume that the pure solvent gas contains no solute. In the freezing-point depression case, we assume that the pure solvent solid contains no solute.
