If molality of the dilute solution is doubled, the value of molal depression constant `(K_f)` will be

A

halved

B

tripled

C

unchanged

D

doubled.

Text Solution

Verified by Experts

The correct Answer is:
C
The value of molal depression constant, Kr.is constant for a particular solvent, thus, it will be unchanged when molality of the dilute solution is doubled.
