Question:
Which of the following aqueous solutions will have the highest freezing point?
Which of the following aqueous solutions will have the highest freezing point?
Show Hint
To compare freezing points, remember that non-electrolytes produce fewer particles in solution, resulting in higher freezing points than electrolytes.

- 1.0 M KCl
- 1.0 M Na2SO4
- 1.0 M glucose
- 1.0 M AlCl3
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The freezing point depression depends on the number of particles in solution. Glucose is a non-electrolyte and does not dissociate, so it produces only one particle per molecule. The ionic compounds, however, dissociate into multiple ions, leading to a greater effect on freezing point depression. Therefore, glucose will have the highest freezing point among the options.
