The molal boiling point constant for water
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. Table 5.3 WebA solution boils at a slightly higher temperature than the pure solvent. The change in the boiling point is calculated from Δ T b = K b m where K b is the molal boiling point constant and m is the concentration of the solute expressed as molality. The boiling point data for some solvents are provided in Table 1.
