Which is a practical application of freezing point depression?

WebWith the formula below, freezing-point depression can be used to measure the degree of dissociation or the molar mass of the solute. This kind of measurement is called cryoscopy (Greek cryo-cold, scopos-observe "observe the cold") and relies on exact measurement of the freezing point. WebThe freezing point may be circumscribed as the fervor at which and liquid and solid stated of a substance have the same vapor pressure. It is observed that the freezer subject off a solution is always lesser than this freezing point is the pure solvent. This is termed as the “depression in freezing point of a solution.”
