Molar Mass Determination by Freezing Point Depression. Students determine the molar mass of an unknown fatty acid dissolved in a known fatty acid using freezing point depression and colligative properties. This lab replaces traditional experiments using hazardous organic solvents. Download Lesson.

Delta T is the freezing point depression, Kf is the freezing point depression constant (in this case it's 20 C/m), and m is the molality of the solution. In this lab the first thing we need to do it determine the delta T. This can be done by using the following equation: Delta T= T1(pure liquid) - T2 (mixed liquid).

The principles of process oriented guided inquiry learning (POGIL) are applied to a binary solid-liquid mixtures experiment.

Consider the situation where a solvent ...The freezing point or melting point of water is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory, the two temperatures would be the same, but ... Colligative properties such as freezing point depression were used to find the molar mass of an unknown compound (nowadays we have more advanced instrumentation / techniques). The overall equation is:Freezing point depression of ice in contact with NaCl aqueous solutions as a function of salt concentration obtained with the Madrid-2019 model, compared to the results for other force fields taken from the literature. The Madrid-2017 16, 17 data were obtained employing force-fields that use TIP4P/2005 for water. For this reason, they provide ...Ethylene glycol (C 2 H 6 O 2) is a molecular compound that is used in many commercial anti-freezes. A water solution of ethylene glycol is used in vehicle radiators to lower its freezing point and thus prevent the water in the radiator from freezing.
