Which of the following statement(s) is/are correct? — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

Statement (a) is incorrect because freezing point depression ($\Delta T_f = K_f \cdot m$) depends on the cryoscopic constant ($K_f$), which varies with the solvent. Statement (b) is the standard formula for osmotic pressure. Statement (c) correctly ranks by van't Hoff factor $i$: $\text{BaCl}_2$ ($i \approx 3$), KCl ($i \approx 2$), $\text{CH}_3\text{COOH}$ (weak acid, $1 < i < 2$), Sucrose ($i = 1$). Statement (d) correctly defines Raoult's law. Therefore, correct answer is B,C,D.
