Question

Two different between positive and negative deviation solution

Answer 1

Non-ideal solutions exhibit eitherpositive or negative deviations from Raoult's law. ... These deviations are caused due to difference in intermolecular forces of attractionbetween solute molecules in pure solute, solvent molecules in pure solvent and solute and solvent in a solution.J

Answer 2

 EXAMPLES OF SOLUTIONS SHOWING POSITIVE DEVIATIONS; 

1) Ethyl alcohol and water
2) Acetone and carbon disulphide
3) Carbon tetrachloride and benzene
4) Acetone and Benzene .

-------------------------------------------------------

EXAMPLES OF SOLUTIONS SHOWING NEGATIVE DEVIATIONS: 

1) HNO3 and water 
2) chloroform and Acetone 
3) Acetic acid and pyridine
4) Hydrochloric acid and water
