\Delta T_{F} = i\times k_{f}\times m

i =  valent cliff factor

everything else remaining save, \Delta T_{F}\: \alpha\: i

KCl, \: i=2

C_{6}H_{12}O_{6} , i =2

Al_{2\left ( SO_{4} \right )_{3}}\:, = 5

K_{2}SO_{4}\:,i=3

\therefore Al_{2}\left (SO_{4} \right )_{3}  will architect largest freezing point desperation.
