Question

Quizplus · Accepted Answer

Colligative properties, such as boiling point elevation and freezing point depression, are dependent only on the number of solute particles relative to solvent particles in a solution. This is known as the "molality" of the solution and is represented by the formula ΔT = K_m * molality, where ΔT is the change in freezing or boiling point, K_m is the molal freezing point depression or boiling point elevation constant, and molality is the number of moles of solute per kilogram of solvent. The molar masses, densities, and hydrated radii of the solute particles are not relevant to these properties. The partial pressure of gases above the solution is only relevant to the vapor pressure lowering colligative property.
