Freezing point of a solution as compared to the solvent is:
Correct answer: A. Lower
- A. Lower
- B. Variable
- C. Higher
- D. Remain the same
Explanation
The freezing point of a solution is generally lower compared to the freezing point of the pure solvent. This happens because when a solute is added to a solvent, it disrupts the arrangement of the solvent particles, making it harder for them to form a solid structure. As a result, the solution needs to be cooled to a lower temperature in order to freeze.

About Colligative Properties
Colligative properties depend on the number of dissolved particles rather than their chemical identity. The topic covers relative lowering of vapour pressure, elevation of boiling point, depression of freezing point and osmotic pressure, including electrolyte dissociation, the van’t Hoff factor and molar-mass calculations.
