Give an example each of miscible liquid pairs showing positive and negative deviations from Raoult’s law. Give reasons for each such deviation.

Solution

The mixtures showing positive and negative deviations are as follows:-

  1. Mixtures showing positive deviation is mixture of ethanol and acetone.

The reason behind this is :- in this case the solute and solvent interactions are weaker than the solute-solute and solvent-solvent interactions.

  • Mixtures showing negative deviation is mixture of chloroform and acetone.

The reason behind this is :- In this case the solute and solvent interactions are stronger than that of the solute – solute interactions or the solvent – solvent interactions .
