. The freezing points of solutions are all lower than that of the pure solvent and is directly proportional to the molality of the solute. Apparatus— the apparatus, an osmometer for freezing point depression measurement, consists of the following:

This kind of measurement is called cryoscopy. Freezing point osmometer knauer is one of the pioneers in the field of osmometry and known for its reliable and user friendly instruments for many decades. The depression is osmolality (# of moles of solute in a kg of water) can be measured by freezing point depression or by vapor pressure osmometers, (5) but also can.

This typically occurs simply because the solute molecules do not fit well in the crystal, i.e.

From the freezing point depression of lauric acid we can determine the molar mass of benzoic acid. Results and repeatability test are best. The freezing point of pure water is 0°c, but that melting point can be depressed by the adding of a solvent such as a salt. The figure below shows the phase diagram for a pure solvent and how it changes when a solute is added to it.
