$Li_2SO_4$

Vedclass · Answer

(A) Double salts are addition compounds that exist only in the solid state and dissociate into their constituent ions when dissolved in water. $Li_2SO_4$ does not form double salts (like alums) because of the exceptionally small size and high polarizing power of the $Li^+$ ion. Due to its small size,$Li^+$ cannot accommodate the coordination requirements necessary to form the stable crystal lattice structure characteristic of double salts,unlike the larger alkali metal ions such as $Na^+$,$K^+$,and $Rb^+$.
