1.Solution and Colligative properties
medium
In mixture $A$ and $B$ components show $-\,ve$ deviation as
A
$\Delta {V_{{\rm{mix}}}} > 0$
B
$\Delta {H_{{\rm{mix}}}} < 0$
C
$A-B$ interaction is weaker than $ A-A$ and $B-B$ interaction
D
$A-B$ interaction is strong than $A-A $ and $B-B $ interaction
(AIEEE-2002)
Solution
In a mixture component $A$ and component $B$ Shows negative Deviation as, $\Delta V _{\text {mixing }}\,<\,0$
i.e. For Negative Deviation, $\Delta V _{\text {mixing }}= O , \Delta H _{\text {mixing }}=- ve$
Because, the forces of attraction between components $A$ and $B$ is greater.
Due to that the tendency of escaping of molecules $AB$ from solution becomes less than that of pure liquids.
$A – B$ attractive forces is greater than $A – A$ and $B – B$ attractive forces.
