Vedclass · Answer

(B) Colligative properties are directly proportional to the van't Hoff factor $(i)$ for solutions of the same concentration.$1.$ For $NaCl$: $NaCl 	o Na^{+} + Cl^{-}$,so $i = 2$.$2.$ For $Na_2SO_4$: $Na_2SO_4 	o 2Na^{+} + SO_4^{2-}$,so $i = 3$.$3.$ For $Na_3PO_4$: $Na_3PO_4 	o 3Na^{+} + PO_4^{3-}$,so $i = 4$.Since the colligative property depends on the number of particles,the order is $NaCl < Na_2SO_4 < Na_3PO_4$ $(2 < 3 < 4)$.

For $0.1 \ M$ solutions of the following electrolytes,the colligative property will follow the order:
