If the molality of the dilute solution is doubled, the value of molal depression constant will be-A. UnchangedB. DoubledC. HalvedD. Tripled
The molal depression constant (also known as the cryoscopic constant or cryoscopic molality constant), often denoted as Kf, is a constant specific to a given solvent. It is used in calculations involving colligative properties, particularly in determining the depression of the freezing point of a solvent due to the presence of a solute.
The value of the molal depression constant (Kf) is a constant for a particular solvent and solute system and does not change when you change the molality (m) of the solution. Therefore, if you double the molality of the dilute solution, the value of the molal depression constant (Kf) will remain unchanged.
So, the correct answer is:
