NEET Chemistry Types of Solutions MCQ Question

Type: MCQ-conceptual-Easy-Class 12

Which of the following statements about solutions and colligative properties is correct?

A

Osmotic pressure is a large colligative property even for very dilute solutions.

B

Isotonic solutions do not have the same osmotic pressure at a given temperature.

C

Colligative properties are independent of the number of solute particles in a solution.

D

The vapour pressure of a solution is always higher than that of the pure solvent.

Correct Answer

Option A

Detailed Explanation

Osmotic pressure is indeed a significant colligative property, particularly in dilute solutions, as mentioned in the context. Isotonic solutions are defined as having the same osmotic pressure, making option B incorrect. Colligative properties depend on the number of solute particles, contradicting option C, and a solution's vapour pressure is always lower than that of the pure solvent, making option D false.
