WebCryoscopic constant. In thermodynamics, the cryoscopic constant, Kf, relates molality to freezing point depression (which is a colligative property ). It is the ratio of the latter to the former: i is the van ‘t Hoff factor, the number of particles the solute splits into or forms when dissolved. b is the molality of the solution. WebThe constant K b is actually derived from several other constants and its derivation is covered in textbooks of introductory thermodynamics. Its technical name is the …

WebSolution. Ebullioscopic constant: Ebullioscopic constant or Molal elevation constant is the elevation in the boiling point produced when one mole of the solute is dissolved in one kilogram of solvent. Its unit is K kg mol -1. Concept: Colligative Properties and Determination of Molar Mass - Elevation of Boiling Point.

Webwhere K b is the boiling point elevation constant, or the ebullioscopic constant and m is the molal concentration (molality) of all solute species. Boiling point elevation constants are characteristic properties that depend on the identity of the solvent. Values of K b for several solvents are listed in Table 5.1.
