WebFeb 27, 2024 · The freezing points away solutions are all lower than such concerning the pure solvent. The freezing point depression is directly proportional to one molality is the solute. The thawing points of solutions are all lower then that of the purified solvent. The thawing point signs are directly proportionally in the molality to and solute.

WebThe change in the vapor pressure that occurs when a solute is added to a solvent is therefore a colligative property. If it depends on the mole fraction of the solute, then it must depend on the ratio of the number of particles of solute to solvent in the solution but not the identity of the solute.

WebMay 27, 2014 · 1 Answer Ernest Z. May 27, 2014 Ionic solutes raise the boiling point more than nonionic solutes at the same concentration do. Boiling point elevation is a colligative property.
