Question
When a nonvolatile solute is dissolved in a liquid solvent, which of the following statements is true (select all of the true statements).
a.The boiling point of the solution will be lower than that of the pure solvent.
The freezing point of the solution will be higher than that of the pure solvent.
The boiling point of the solution will be higher than that of the pure solvent.
The freezing point of the solution will be lower than that of the pure solvent.
a.The boiling point of the solution will be lower than that of the pure solvent.
b.The freezing point of the solution will be higher than that of the pure solvent.
c.The boiling point of the solution will be higher than that of the pure solvent.
d.The freezing point of the solution will be lower than that of the pure solvent.
Explanation / Answer
adding a non volatile solute does 3 things:
increases boiling point
decreases freezing point
decreases vapour pressure
Here question is asking about boiling and freezing point
Hence the correct answer is:
c,d
