Define solution, solvent and solute.

Define Raoult's law for lowering of vapour pressure. How is the law useful in determining the molecular weight of a solvent when a known non - volatile solute is dissolved ?

The van't Hoff factor i for a compound which undergoes dissociation in one solvent and association in other solvent is respectively

Diethyl ether is mostly used in solvent extraction due to the following reasons

Write short notes on a) Fractional crystallisation b) Solvent extraction

Define vapour pressure. How is it dependent on nature of solvent and temperature?

Identify the solvent.

The measurement of amount of solute that dissolves in a solvent is

A non-volatile solute (A) is dissolved in a volatile solvent (B). The vapour pressure of the resultant solution is P_(s^(*)) . The vapour pressure of pure solvent is P_(B)^(@) . If X_(B) is the mole fraction of the solvent, which of the following is correct?
