  2. Freezing-point depression - Wikipedia

    en.wikipedia.org/wiki/Freezing-point_depression

    The phenomenon of freezing-point depression has many practical uses. The radiator fluid in an automobile is a mixture of water and ethylene glycol. The freezing-point depression prevents radiators from freezing in winter. Road salting takes advantage of this effect to lower the freezing point of the ice it is placed on.

  3. Freezing point depression osmometer - Wikipedia

    en.wikipedia.org/wiki/Freezing_point_depression...

    The osmometer uses the solution's freezing point depression to establish its strength. It is also used to determine the level of osmotically appropriate body fluid in various chemicals dissolved in the blood using the relationship in which a mole of dissolved substance reduces the freezing point of a kilogram of water by 1.86 °C (35.35 °F ...

  4. Cryoscopic constant - Wikipedia

    en.wikipedia.org/wiki/Cryoscopic_constant

    Through cryoscopy, a known constant can be used to calculate an unknown molar mass. The term "cryoscopy" means "freezing measurement" in Greek. Freezing point depression is a colligative property, so ΔT depends only on the number of solute particles dissolved

  6. Slurry ice - Wikipedia

    en.wikipedia.org/wiki/Slurry_ice

    Slurry ice with propylene glycol as depressant viewed through a microscope.. Slurry ice is a phase changing refrigerant made up of millions of ice "micro-crystals" (typically 0.1 to 1 mm in diameter) formed and suspended within a solution of water and a freezing point depressant.

  7. Plasma osmolality - Wikipedia

    en.wikipedia.org/wiki/Plasma_Osmolality

    The difference in units is attributed to the difference in the way that blood solutes are measured in the laboratory versus the way they are calculated. The laboratory value measures the freezing point depression, properly called osmolality while the calculated value is given in units of osmolarity. Even though these values are presented in ...

  8. Osmometer - Wikipedia

    en.wikipedia.org/wiki/Osmometer

    An osmometer is a device for measuring the osmotic strength of a solution, colloid, or compound.. There are several different techniques employed in osmometry: Freezing point depression osmometers may also be used to determine the osmotic strength of a solution, as osmotically active compounds depress the freezing point of a solution.

  9. Van 't Hoff factor - Wikipedia

    en.wikipedia.org/wiki/Van_'t_Hoff_factor

    The van 't Hoff factor i (named after Dutch chemist Jacobus Henricus van 't Hoff) is a measure of the effect of a solute on colligative properties such as osmotic pressure, relative lowering in vapor pressure, boiling-point elevation and freezing-point depression.
