The addition of a polar solvent to a solid electrolyte results in:

For a dilute solution of $K_3[Fe(CN)_6]$,the van't Hoff factor $(i)$ is ..... [assuming $100\%$ ionization]

An aqueous solution of a salt $MX_2$ at a certain temperature has a van't Hoff factor of $2$. The degree of dissociation for this solution of the salt is

At a certain temperature,the vapour pressure of pure water is $76 \ mm$ of $Hg$. When $1 \ mol$ of $Na_2SO_4$ is dissolved in $36 \ mL$ of water,the vapour pressure of the solution becomes $38 \ mm$ of $Hg$. What is the percentage dissociation of $Na_2SO_4$ in the solution?

The Van't Hoff factor of $Ca(NO_3)_2$ is

When $Hg(CN)_2$ is added to a solution of completely ionized $KCN$,the following reaction occurs: $2KCN + Hg(CN)_2 \to K_2[Hg(CN)_4]$. Due to the formation of this complex,which of the following occurs?
