Question

The boiling point of a solvent containing a non volatile solute is depresses or elevated or does not change plz answere fast

Answer 1

The vapour pressure of the solution of a non volatile solute is always less than the vapour pressure of pure solvent . The dissolved non volatile solute lower the v.p. and hence it is necessary to increase it's v.p. to make it equal to the atmospheric pressure by raising the temperature .Thus solution always boils at higher temperature than pure solvent ...

The boiling point of a solvent containing a non volatile solute is elevated
