Van't Hoff factor of $Hg_{2}Cl_{2}$ in its aqueous solution will be : ($Hg_{2}Cl_{2}$ is $80\%$ ionized in the solution) :- (in $.6$)

The freezing point of equimolal aqueous solution will be highest for

What will be the osmotic pressure in $atm$ of a $0.2 \ M$ $K_4[Fe(CN)_6]$ solution at $27 \ ^oC$?

For a $0.01 \ m$ aqueous solution of $K_4[Fe(CN)_6]$,if $K_b = 0.52 \ K \ kg \ mol^{-1}$ for the solvent,then its boiling point will be ..... $^\circ C$.

The elevation in boiling point of a solution of $13.44 \ g$ of $CuCl_2$ in $1 \ kg$ of water using the following information will be (Molecular weight of $CuCl_2 = 134.4 \ g \ mol^{-1}$ and $K_b = 0.52 \ K \ kg \ mol^{-1}$)

The Van't Hoff factor for sodium phosphate would be
