Question

Which of the following aqueous solution has highest freezing point ? (A) 0.1 molal Al2(SO4)3 (B) 0.1 molal BaCl2 (C) 0.1 molal Al2Cl3 (D) 0.1 molal NH4Cl

Colligative property α number of particles after dissociation or association means less be the number of particles, more lower be the freezing point and more be the number of particle more lower be the freezing pöint. Hence for NH 4 Cl , n=i=2 which is gives least number of particle hence show highest freezing point.
