NEET Chemistry Raoult's Law MCQ Question
Which of the following statements about colligative properties and solutions is correct?
The addition of a non-volatile solute decreases the vapour pressure of the solvent.
The freezing point of a solution is higher than that of the pure solvent.
Raoult's law applies only to solutions containing volatile solutes.
The molality of a solution is independent of the mass of the solvent used.
Correct Answer
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.
