Question

cryoscopic constant depends on
a)nature of solvent
b)nature of solute
c) nature of solution
d)number of solvent molecules​

Answer 1

Answer:

(B)

Explanation:

Cryoscopic constant may be defined as the depression in freezing point when one mole of non-volatile solute is dissolved in one kg of solvent. It may also be defined as the molal depreesionconstant . It depends on the malar mass of the solute in the solution.

Answer 2

Answer:

The correct option is (b) Nature of solute.

The cryoscopic constant depends on the molar mass of solute molecules.

Explanation:

Cryoscopic constant, also called molal depression constant is a depression at freezing point containing one-mole non-volatile solute in 1 kg of solvent.

The depression at the freezing point is a colligative phenomenon, and the temperature difference depends only on the number of dissolved solvent particles. It is described by $\symup\Delta T_{f} = i\times K_{f} \times m$

The SI unit of the Cryoscopic constant is $K \ kg\ mol^{-1}$.

The cryoscopic constant depends on the molar mass of solute molecules.
Hence, option (b) is correct.
