Question

Read the following statements carefully and choose the correct option
(i) Osmotic pressure is not a colligative property.
(ii) For dilute solutions, osmotic pressure is proportional to the molarity, $C$ of the solution at a given temperature $T$.
(iii) During osmosis, solvent molecules always flow from higher concentration to lower concentration of solution.
(iv) The osmotic pressure has been found to depend on the concentration of the solution

• A. (i), (ii) and (iv) are correct
• B. (ii) and (iv) are correct
• C. (iii), and (iv) are correct
• D. (i), (ii) and (iii) are correct

Answer 1

Answer: (B)

Osmotic pressure is a colligative property as it depends on the number of solute molecules and not on their identity. For dilute solutions, during osmosis solvent molecules always flow from lower concentration to higher concentration of solution.
