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

Examples

• The chemistry lab performed several cryoscopies to measure the colligative properties of the salt solutions.
• Cryoscopies are commonly used in analytical chemistry to determine the purity of compounds.
• The students conducted cryoscopies as part of their physical chemistry experiment.
• Modern cryoscopies employ precise thermometers to detect even small changes in freezing point.
