Vedclass · Answer

(D) The depression in freezing point $(\Delta T_f)$ is a colligative property,which is directly proportional to the van't Hoff factor $(i)$.$(i)$ For $K_2Cr_2O_7$,$i = 3$ $(2K^+ + Cr_2O_7^{2-})$.$(ii)$ For $NH_4Cl$,$i = 2$ $(NH_4^+ + Cl^-)$.$(iii)$ For $BaSO_4$,$i = 2$ $(Ba^{2+} + SO_4^{2-})$.$(iv)$ For $Al_2(SO_4)_3$,$i = 5$ $(2Al^{3+} + 3SO_4^{2-})$.Since $Al_2(SO_4)_3$ produces the maximum number of particles $(i = 5)$,it will show the maximum depression in freezing point,resulting in the minimum freezing point.
