Match the solutions in Column I with their osmotic properties in Column II — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

(A) Both glucose and urea are non-electrolytes at 0.1 M, so they have identical osmotic pressures and are isotonic (P). (B) $S_1$ (NaCl) yields $0.2 \text{ M}$ ions while $S_2$ ($\text{Na}_2\text{SO}_4$) yields $0.3 \text{ M}$ ions, making $S_1$ hypotonic to $S_2$ (R). (C) Both NaCl and KCl yield 2 ions, giving $0.2 \text{ M}$ effective concentration, so they are isotonic (P). (D) $S_1$ ($\text{CuSO}_4$) yields $0.2 \text{ M}$ ions while $S_2$ (sucrose) remains $0.1 \text{ M}$, making $S_1$ hypertonic (Q). Therefore, correct answer is A-P, B-R, C-P, D-Q.
