Which of the following aqueous solutions exhibits the minimum freezing point depression upon complete dissociation?

If a centimolal aqueous solution of $K_{3}[Fe(CN)_{6}]$ has a degree of dissociation of $0.78$,what is the value of the van't Hoff factor?

In a $0.2 \ molal$ aqueous solution of a weak acid $HX$,the degree of ionisation is $0.25$. The freezing point of the solution will be nearest to ......... $^oC$. $(K_f = 1.86 \ K \ kg \ mol^{-1})$

When $9.45 \text{ g}$ of $ClCH_2COOH$ is added to $500 \text{ mL}$ of water,its freezing point drops by $0.5^\circ \text{C}$. The dissociation constant of $ClCH_2COOH$ is $x \times 10^{-3}$. The value of $x$ is ............... (Rounded off to the nearest integer) $[K_{f(H_2O)} = 1.86 \text{ K kg mol}^{-1}]$

Which of the following solutes has the ratio of theoretical molar mass to the experimentally observed molar mass equal to $3$?

If $BaCl_2$ ionizes to an extent of $80 \%$ in aqueous solution, the value of van't Hoff factor is
