Question

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. $\ge$ 80ml

Answer 1

The correct option is B <80 ml

As per question, $\text{the chloroform \& acetone form a non-ideal solution and the they shows negative deviation.}$ That means,

$\Delta V_{mix}=-ve$

$\Delta H_{mix}=-ve$

$\text{So, the total volume of solution = less than (30 + 50 ml) or less than 80 ml or < 80 ml}$
