The elevation of boiling point is a colligative property of matter which means that it depends on the solvent-to-solvent ratio but not on the nature of the solute. This Demonstration shows the boiling point elevation from solute and solvent data. By accepting, you agree to the updated privacy policy. Why elevation in boiling point is a colligative property? Find points on land and at sea. At higher elevations, and thus a lower atmospheric pressure, a liquid will boil at a lower temperature, as less heat is required to increase the vapor pressure to the atmospheric pressure. Tap here to review the details. The equation is: T b = i K b m. In van't Hoff factor, i , the moles of particles per . bB where T b is the boiling point elevation K b is the ebullioscopic constant, which depends on the solvent bB is the molality of the solution (typically found in a table) The difference between freezing point depression and boiling point elevation is that freezing point depression decreases the freezing point of a solution whereas boiling point elevation increases the boiling point of a solution.
