The cryoscopic constant is denoted by kf
It is the depression of the freezing point of the solvent produced on dissolving one mole of a substance in 1000g of it. It is also called molal depression constant. It may also be defined as the molal depression constant. The cryoscopic constant is denoted by kf.
- The Kf for water is 1.853 K kg mol−1.
- The value of kf depends on the nature of solvent only as its characteristic constant.
