Question

A non ideal solution was prepared by mixing 30ml chloroform and 50ml acetone. The volume of mixture will be :

• A. $>80ml$
• B. $<80ml$
• C. $=80ml$
• D. $\ge 80ml$

Answer 1

The correct option is B $<80ml$

A mixture of chloroform and acetone shows a negative deviation from Raoult's law.

For such a solution $\Delta V_{mixture}<0$ or $V_t<(30+50)ml$.

Option B is correct.
