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?

The boiling point of $0.001 \ M$ aqueous solutions of $NaCl$,$Na_{2}SO_{4}$,$K_{3}PO_{4}$ and $CH_{3}COOH$ should follow the order.

In comparison to a $0.01 \ M$ solution of glucose,the depression in freezing point of a $0.01 \ M \ MgCl_2$ solution is (Molecular weight of $MgCl_2 = 95$,molecular weight of glucose $= 180$).

Which of the following compounds has a Van't Hoff factor $i$ equal to $2$ for a dilute solution?

Calculate the van't Hoff factor $(i)$ of a centimolar solution of potassium ferrocyanide $(K_4[Fe(CN)_6])$ if it is $60\%$ dissociated at $300\text{ K}$.

Which one of the following $0.06 \ M$ aqueous solutions has the lowest freezing point?
