Question
Why should a solution of a non-volatile solute boil at a higher temperature ? Draw the diagram to prove your point?
Solution
Answer:
Boiling point is that temperature at which the vapour pressure of the solution becomes equal to the external pressure since on adding a nonvolatile solute, the vapour pressure of the solution gets lowered, therefore, it will boil at a higher temperature.
