Solutions Question 291

Question: Two solutions of KNO3 and CH3COOH are prepared separately. Molarity of both is 0.1,M and osmotic pressures are P1 and P2 respectively. The correct relationship between the osmotic pressures is [CPMT 1983, 84; Pb CET 2004]

Options:

A) P2>P1

B) P1=P2

C) P1>P2

D) P1P1+P2=P2P1+P2

Show Answer

Answer:

Correct Answer: C

Solution:

KNO3 dissociates completely while CH3COOH dissociates to a small extent. Hence, P1>P2 .
