The Raoult’s Law stated that the mole fraction of a solute was proportional to the partial pressure of the solute.
Ideal Solutions:
- The ideal solution obeyed Raoult’s Law for all concentrations.
- The ideal solutions form intermolecular force of attraction between all the molecules.
- Thus, the interaction between the solute-solute molecules and the solvent-solvent molecules was similar to the interaction between the solute and solvent molecules.
- This phenomenon was noted in acetone and benzene solution and hence, it was called as an ideal solution
Non-ideal solutions:
- On the other hand, the chloroform and acetone solution showed a negative deviation from the Raoult’s Law and was an non-ideal solution.
- In these solutions, the attractive forces noted between the solute-solute and solvent-solvent molecules were weaker than those noted for the solute-solvent molecules.
- They also showed a lower vapor pressure.
