Question:

Arrange the following in increasing order of their osmotic pressure generation at 298 K:
(The cell wall is permeable to water and not to the solute molecules)
(A) If a cell containing 0.5 moles of solute dissolved in 1 L of water is immersed in pure water.
(B) If a cell containing 0.25 moles of solute dissolved in 1 L of water is immersed in pure water.
(C) If a cell containing 0.1 moles of solute dissolved in 0.01 L of water is immersed in pure water.
(D) If a cell containing 0.2 moles of solute dissolved in 0.05 L of water is immersed in pure water.

The Correct Option is A

Solution and Explanation

Osmotic pressure is directly proportional to the concentration of solute. Higher molarity results in higher osmotic pressure. Therefore, the increasing order of osmotic pressure is (C) < (B) < (A) < (D).
