Two liquids `A` and`B` on mixing produce a warm solution. Which type of deviation from Raoult's law does it show?

Explanation

(i) On mixing Liquid X and Liquid Y, volume of the resulting solution decreases. Negative deviation shown by the resulting solution in which
`F_(X-Y)gtF_(X-X) and F_(Y-Y)`
Due to this there is decrease in the escaping tendency of X or Y molecules from the surface of solution. `DeltaH_(mix)` is (-)ve. Hence evolution of heat takes place. Hence temp of resulting solution increases. Consequently, the vapour pressure of the solution will be lower.
(ii) When we place the blood cell in water (hypotonic solution), they would swell due to osomsis and may even burst.
