Which of the following `0.1 M` aqueous solutions will have the lowest freezing point?

A

Potassium sulphate

B

Sodium chloride

C

Urea

D

Glucose

Text Solution

Verified by Experts

The correct Answer is:
A
Urea and glucose do not dissociate in solution. Sodium chloride gives two ions and potassium sulphate gives three ions per formula unit. Therefore, the effective number of particles is maximum in potassium sulphate, and it shows the maximum depression in freezing point.
