Freezing point depression and boiling point

WebFreezing point depression is the lowering of the equilibrium freezing or melting temperature by solutes in the liquid phase. Solutes in the liquid phase also raise the equilibrium boiling temperature. Pressure also affects freezing temperature (a little) and boiling temperatures (a lot). WebExamples include boiling point and osmotic pressure. This relationship is shown through the equation Δt = Kf × m. Δt is the freezing point depression, Kf is the freezing point depression constant for a particular solvent 3.9°C•kg/mol for lauric acid, and m is the molality of the solution. I n this experiment, the freezing temperature of the pure solvent, …

Both the boiling point elevation and the freezing point … WebΔTf = (1.86 C/m) × (0.6 m) × 3 = 3.348 C. The freezing point depression is the difference between the freezing point of pure water (0°C) and the freezing point of the solution: Freezing point of solution = 0 ° C − Δ T f = 0 ° C − 3.348 ° C = − 3.348 ° C. Therefore, the freezing point of the solution is -3.348°C.
