'depression of freezing point' značenje u engleski leksikon

Množina: depression of freezing points

Lowering of a solution’s freezing point below that of the pure solvent; it depends on the number of molecules of solute dissolved in it. For a single solvent, such as pure water, all solute substances in the same molar concentration produce the same lowering of freezing point. The depression d produced by the presence of a solute of molar concentration C is given by the equation d = KC, where K is a constant (called the cryoscopic constant) for the solvent concerned.
Measurement of freezing-point depression is a useful method of determining the molecular weights of solutes. It is also used to detect the illicit addition of water to milk.
