1. the determination of the freezing point of a liquid, especially to find the molecular weight of a dissolved substance or to detect impurities.
Usage: technical; chemistry

Examples

• Cryoscopy is used in chemistry labs to measure the colligative properties of solutions.
• The student performed cryoscopy to determine the molar mass of an unknown compound.
• By using cryoscopy, scientists can detect the presence of dissolved salts in water samples.
• Cryoscopy relies on the principle that dissolved solutes lower the freezing point of a solvent.
