Correct Statement about Colligative Properties of Solutions

Introduction: Colligative properties of solutions depend only on the number of solute particles present in the solution, and not on their nature.

Correct Statement: (D) All of the above.

Explanation:

(A) b. The van't Hoff factor (i) of NaCl is 2, while that of sucrose is 1. Therefore, the osmotic pressure of 1 molal NaCl solution is twice that of 1 molal sucrose solution.

(B) b.p. elevation is directly proportional to the molality of the solute. The proportionality constant is called the molal elevation constant (Kb) and is specific to the solvent. The Kb of glucose is half that of KCl. Therefore, the b.p. elevation of 1 molal glucose solution is half that of 1 molal KCl solution.

(C) b.p. is a colligative property because it depends only on the number of solute particles present in the solution, and not on their nature.

Therefore, the correct statement is (D) All of the above.
