NEET Chemistry Van't Hoff Factor MCQ Question
Which of the following statements about the colligative properties and the behavior of solutions is correct?
The molar mass of a solute can be calculated using the freezing point depression constant and the depression in freezing point.
Solutes that associate in solution will always increase the colligative properties more than those that dissociate.
Azeotropes are formed when solutions deviate positively from Raoult's law.
The van't Hoff factor is always equal to the number of particles in solution regardless of the type of solute.
Correct Answer
Detailed Explanation
The molar mass of a solute can indeed be determined using freezing point depression, as indicated in the equations provided in the NCERT context. Statements B, C, and D reflect misconceptions about solute behavior and colligative properties.
