WebMay 20, 2024 · Freezing Point Depression. The effect of adding a solute to a solvent has the opposite effect on the freezing point of a solution as it does on the boiling point. A solution will have a lower freezing point than a pure solvent. The freezing point is the temperature at which the liquid changes to a solid. At a given temperature, if a substance ... WebMay 17, 2013 · $\begingroup$ It's a little weird that you're trying to justify changes in the melting point by looking at the effects of dissolved substances on the boiling point. If you have a book around, take a quick look again at freezing point depression (or cryoscopic effect) and compare it with the boiling point elevation (or ebulioscopic effect). hollow shaft gearbox
