1.Solution and Colligative properties
medium
A non ideal solution was prepared by mixing $30\,ml$ chloroform and $50\,ml$ acetone. The volume of mixture will be
A
$> 80\,ml$
B
$< 80\,ml$
C
$= 80\,ml$
D
$> 80\,ml$
Solution
(b)Chloroform and acetone form a non-ideal solution, in which $A…..B$ type interaction are more than $A……A$ and $B……B$ type interaction due to $H$-bonding.
Hence, the solution shows, negative deviation from Raoult’s Law i.e.,
$\Delta {V_{mix}} = – ve$; $\Delta {H_{mix}} = – \,ve$
$\therefore $ total volume of solution = less than $(30 + 50\,ml)$
or $ < \,80\,ml$
