Cryoscopic constant of a liquid is:

A

decreases in freezing point when 1 gram of solute is dissolved per kg of the solvent

B

decreases in the dreezing point when 1 mole of solute is dissolved per kg of the solvent

C

the elevation for 1 molar solution

D

a factor used for calculation of elevation in boiling point

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaT_(f) = K_(f), m`
If `m = 1, DeltaT_(f) = K_(f)`
