  3. Colligative properties - Wikipedia

    en.wikipedia.org/wiki/Colligative_properties

    Freezing point depression and boiling point elevation In chemistry , colligative properties are those properties of solutions that depend on the ratio of the number of solute particles to the number of solvent particles in a solution, and not on the nature of the chemical species present.

  4. Cryoscopic constant - Wikipedia

    en.wikipedia.org/wiki/Cryoscopic_constant

    R is the ideal gas constant. M is the molar mass of the solvent. T f is the freezing point of the pure solvent in kelvin. ΔH fus is the molar enthalpy of fusion of the solvent. The K f for water is 1.853 K kg mol −1. [1]

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  6. Freezing-point depression - Wikipedia

    en.wikipedia.org/wiki/Freezing-point_depression

    In the above equation, T F is the normal freezing point of the pure solvent (273 K for water, for example); a liq is the activity of the solvent in the solution (water activity for aqueous solution); ΔH fus T F is the enthalpy change of fusion of the pure solvent at T F, which is 333.6 J/g for water at 273 K; ΔC fus p is the difference ...
