Discuss on the vapour pressure of solutiosn of solids in liquids.

The vapour pressure is least for

Define vapour pressure of a liquid.

Discuss the concept of vapour pressure.

What is vapour pressure of a liquid ?

Discuss the factors affecting solubility of solid in a liquid.

Assertion: The pressure exerted by the vapour of a liquid at equilibrium at a given temperature is called its vapour pressure. Reason: If a nonvolatile solute is added to a solvent to give a solution, the vapour pressure of the solution is found to be greater than the vapour pressure of the pure solvent.

The vapour pressure of a solution containing non volatile solute is less than the vapour pressure of pure of solvent. Give reason.

Which of the following statements are correct (a) the boiling point of a solution is greater than pure solvent (b) the temperature where the vapour pressure of liquid equals to atmospheric pressure is called its boiling point (c) the vapour pressure of pure solvent is less than the vapour pressure of solution containing non volatile solute. (d) the temperature of liquid remained in the container after evaporation is more than before the evaparation
