Q. Two solutions of $KNO_{3}$ and $CH_{3}COOH$ are prepared separately. Molarity of both is 0.1 M and osmatic pressures are $p_{1}$ and $p_{2}$respectively. The correct relationship between the osmatic pressures is
A) $p_{1} = p_{2}$
B) $p_{1} > p_{2}$
C) $p_{2} > p_{1}$
D) $\frac{p_{1}}{p_{1} + p_{2}} + \frac{p_{2}}{p_{1} + p_{2}}$
Explanation
(b)
$KNO_{3}$ dissociates completely while $CH_{3}COOH$ dissociates to a small extent hence,${\ p}_{1} > p_{2}$
