The molal freezing point depression constant of equimolar KCl-AlCl3 melts was estimated to be 27 ± 2°C kg mol-1. The enthalpy of freezing for KAlCl4 was found to be 18.0 ± 1.2 kJ mol-1, in good agreement with the ... RW Berg,HA Hjuler,NJ Bjerrum - 《Inorganic Chemistry》 被引...
The formula for depression in freezing point is given by: ΔTf=Kf⋅m where: - ΔTf = depression in freezing point - Kf = cryoscopic constant for the solvent (water in this case) - m = molality of the solution 2. Setting the Condition: We need to find the condition under which: ...
Kf= cryoscopic constant (1.86°C kg/mol for the freezing point of water) i = Van't Hoff factor Freezing Point Depression in Everyday Life Freezing point depression has interesting and useful applications. When salt is put on an icy road, the salt mixes with a small amount of liquid water...

If the freezing point depression of water is -1.86 degrees/m, what would be the freezing point of this solution? What is the freezing point of an aqueous 0.20 M NaCl solution? What is the freezing point of a 0.27 M solution of glucose, C6H12O6, in water? (Kf for water is 1.858 c/...
Our results are in excellent agreement with the experimental freezing point depression showing that the set of parameters used in this work for the water and NaCl is a very good choice to reproduce the thermodynamic properties of the water/NaCl system with molecular dynamics simulations....
