cryoscopy

Cryoscopy is a scientific technique used to determine the freezing point of a liquid. It involves cooling the liquid until it solidifies (freezes). By measuring the temperature at which this happens, scientists can analyze properties like concentration or purity, as impurities or solutes lower the freezing point. This method is useful in chemistry and medicine, for example, to assess the concentration of solutions or the purity of substances like water or blood plasma. In essence, cryoscopy provides insights into the composition of a liquid by observing its freezing behavior.
