WebApr 6, 2024 · Freezing point depression can be defined as the phenomenon of lowering the freezing point of any solvents after the addition of solutes. From this freezing point depression definition, it must be clear that this is a colligative property of solutions. WebMay 8, 2016 · The decrease in freezing point ΔT f0 = T f0 – T f is known as depression in freezing point. For dilute solutions, the depression in freezing point (ΔT f) is directly proportional to the molal concentration of the solute in a solution (Molality). Thus, Where, m = molality i.e. the number of moles of solute dissolved in 1 kg of solvent.
WebApr 9, 2024 · In the freezing bespeak depression graph shown in Effigy 1: Bend BC represents the vapor pressure of the pure solvent; Curve DE represents the vapor pressure of the solution; and Bend AB represents the vapor pressure of the solid (frozen state). Figure 1: Freezing point depression graph. WebFreezing point depression is the phenomena that describes why adding a solute to a solvent results in the lowering of the freezing point of the solvent. When a substance starts to freeze, the molecules slow down due to the decreases in temperature, and the intermolecular forces start to take over.
