Equimolar solutions in the same solvent have:
Correct answer: B. Same boiling and same freezing points
- A. Different boiling and different freezing points
- B. Same boiling and same freezing points
- C. Same freezing point but different boiling points
- D. Same boiling point but different freezing points
Explanation
The elevation in the boiling point and the depression in the freezing point are colligative properties and depend on the number of solute particles.Equimolar solutions of non-electrolytes have the same number of solute particles.Hence, equimolar solutions of two non-electrolytes in the same solvent have the same boiling point and same freezing point.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
