Chemistry-Raoult's Law
NEET Chemistry Raoult's Law MCQ Question
Type: MCQ-conceptual-Hard-Class 12
Which of the following statements about colligative properties and solutions is correct?
A
The addition of a non-volatile solute decreases the vapour pressure of the solvent.
B
The freezing point of a solution is higher than that of the pure solvent.
C
Raoult's law applies only to solutions containing volatile solutes.
D
The molality of a solution is independent of the mass of the solvent used.
Correct Answer
Option A
Detailed Explanation
The addition of a non-volatile solute decreases the vapour pressure of the solvent, leading to a lower freezing point, as stated in the NCERT context. This aligns with Raoult's law, which describes the relationship between the vapour pressure and the presence of solute particles.
