Statement 1: Two sucrose solutions of same molality prepared in different solvents will have the same freezing point depression
Statement 2: Different solvents will have different value of `K_(f)`

A

Statement 1 is True, Statement 2 is true, Statement 2 is correct explanation for Statement 1

B

Statement 1 is True, Statement 2 is True, Statement 2 is NOT a correct explanation for Statement 1

C

Statement 1 is True, Statement 2 is False

D

Statement 1 is False, Statement 2 is True

Text Solution

Verified by Experts

The correct Answer is:
D
`Delta T_(f)= K_(f)M` Differetn solvents will have different value of `K_(f)`. So `Delta T_(f)` for the two solution of sucrose will be different
