Same boiling point and freezing point

Vedclass · Answer

(D) Colligative properties like elevation in boiling point $(\Delta T_b)$ and depression in freezing point $(\Delta T_f)$ depend only on the number of solute particles in the solution.For equimolar solutions (same concentration) in the same solvent,the number of solute particles is the same.Therefore,the elevation in boiling point and the depression in freezing point will be the same for all such solutions.Since $\Delta T_b = T_b - T_b^0$ and $\Delta T_f = T_f^0 - T_f$,if $\Delta T_b$ and $\Delta T_f$ are constant,then the boiling point $(T_b)$ and freezing point $(T_f)$ of the solutions will also be the same.
