The units … WebColligative Properties: I. Introduction. A colligative property of a solution, freezing-point depression, is used in this experiment to determine the molecular weight of an unknown compound A. The freezing-point of a solution is always lower than the freezing-point of the pure solvent. The magnitude of the freezing-point depression ( D T f) is ...
WebMar 13, 2024 · Boiling point elevation depends on the identity of the solvent and the concentration of solute particles, but not the identity of the solute. Consequently, just like freezing point depression, boiling point elevation can be used to determine the molar mass of a solute. If the solution is an electrolyte -- one containing a substance like …
