NEET Chemistry Colligative Properties MCQ Question
Consider a diagram where the vapor pressure of a pure solvent and a solution containing a non-volatile solute is plotted against temperature. Which label correctly represents the freezing point of the solution?
Point A, where the vapor pressure of the solution equals that of the pure solid solvent.
Point B, where the vapor pressure of the pure solvent is highest.
Point C, where the vapor pressure of the pure solvent equals that of the solution.
Point D, where the vapor pressure of the solution is highest.
Correct Answer
Detailed Explanation
The freezing point of the solution is reached when the vapor pressure of the solution equals that of the pure solid solvent, as per the explanation of freezing point depression in the NCERT context.
