Determine freezing point of solution
Did you know?
WebDue to a decrease in vapour pressure of the liquid phase, it becomes equal to the vapour pressure of solid at a lower temperature. The difference in the freezing point of pure solvent and that of the solution is known as depression in the freezing point. ∆ T f = Freezing point pure solvent - Freezing point of solvent after addition of solvent.
Web1 Answer. If you were to freeze the solution in a normal manner, using something similar to a home freezer, a more and more concentrated solution will form as the majority of the solvent freezes. The solute will be found in a small amount of solution that did not freeze, since the solute allows for freezing point depression.
