Question

Q.3State Raoult’s law. How is it formulated for solutions of volatile solutes?​

Answer 1

Answer:

Raoult's law for solution of non-volatile solution : The relative lowering of vapour pressure for a solution is equal to the mole fraction of solute when solvent alone is volatile.

Answer 2

Answer:

Raoult's law states that the vapor pressure of a solvent above a solution is equal to the vapor pressure of the pure solvent at the same temperature scaled by the mole fraction of the solvent present: Psolution=χsolventPosolvent.

Formula

P_{\text{solution }}=X_{\text{solvent }} P_{\text{solvent }}

P_{\text{solution }} = vapor pressure of the solution

X_{\text{solvent }} = mole fraction of the solvent

P_{\text{solvent }} = vapor pressure of the pure solvent
