When non-ideal solution was prepared by mixing 30 mL chloroform and 50 mL acetone. The volume of mixture will be

Options

A. `gt 80 ml`
B. `lt 80 ml`
C. `= 80 ml`
D. none of these

Explanation

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`
total volume of solution = less than (30 + 50 ml) or `lt 80 ml`
