Boiling Point Elevation and Freezing Point Depression (13.3.2) Flashcards
• As solute is added to a solvent, the vapor pressure of the solvent decreases, increasing the boiling point of the solution.
• As solute is added to a solvent, the vapor pressure of the solvent decreases, increasing the boiling point of the solution.
• As more solute is added and the vapor pressure drops, the triple point of the solution decreases causing a depression in the freezing point.
• As more solute is added and the vapor pressure drops, the triple point of the solution decreases causing a depression in the freezing point.
• Mathematical relationships relating the concentration of solute to the change in freezing or boiling point are ∆Tf = – Kfm and ∆Tb = Kbm.
