Boiling occurs when vapour pressure of a liquid equals surrounding pressure, now since solute is added to the solvent (liq) the vapour pressure decreases and melting point also decreases. Hence a greater temperature is required for the vapour pressure to reach surrounding pressure and hence boiling point increases.

The decrease in the vapor pressure of the solvent that occurs when a solute is added to the solvent causes an increase in the boiling point and decrease in the melting point of the solution. According to this figure, the solution can't boil at the same temperature as the pure solvent.

@Rinku @Ahmad @Kishor.
You guys saying pressure and Boiling point relationship.
Less vapour pressure means high boiling liquid. Am I right?

After add the solute to solvent the vapour pressure will be reduce and so boiling point will increase and freezing point will decrease.

I think, from my point of view, boiling Point increases of fluid with increase in concentration of solute in solvent.

If vapor pressure decreases boiling point should decrease. Correct me if I am wrong.

Vapour pressure is inversely proportional to the boiling point.
