On addition of solute in the solvent, the ______________ of the solution decreases ?
Correct answer: D. Both B. and C.
- A. Boiling point
- B. Freezing point
- C. Vapour pressure
- D. Both B. and C.
Explanation
A dissolved nonvolatile solute lowers the solvent’s vapour pressure and consequently lowers the freezing point, while raising the boiling point. Thus both freezing point and vapour pressure decrease.
