Pure water can be obtained from sea water by

The vapour pressure of two liquids P and Q are 80 and 60 torr, respectively. The total vapour pressure of solution obtained by mixing 3 moles of p and 3 mols of Q would be.

In cold countries, ethylene glycol is added to water in the radiators of cars during winter. This results in

Formation of a solution from two components can be considered as

1. Pure solve → separated solvent molecules, ΔH₃
2. ICl₃ solvent → separated solute molecules, ΔH₂
3. Separated solvent and solute molecules → solution, ΔH₃

Solution so formed will be ideal, if

 Which one is a colligative property?

Acetic acid is dissolved in benzene, and the molecular mass is determined from the elevation of boiling point. The molecular mass obtained will be ........   (Assume complete dimerisation of acetic acid in benzene)

The lowest vapour pressure is exerted by

The van't Hoff factor for an aqueous solution of Al₂(SO₄)₃ is

Out of the following which is not a colligative property?

The vapour pressure, at a given temperature, of an ideal solution containing 0.2 mole of a non volatile solute and 0.8 mole of solvent is 60 mm of Hg. The vapour pressure of the pure solvent at the same temperature is
