Among the following 0.10 m aqueous solutions, which one will exhibit the largest freezing point depression?

Options

A. `K_(2)SO_(4)`
B. KCl
C. `C_(6)H_(12)O_(6)`
D. `Al_(2)(SO_(4))_(3)`

Answer

D

Explanation

Considering complete ionization `(alpha = 1)`
Vant Hoff.s factor i for
`K_(2)SO_(4)=3, KCl=2, C_(6)H_(12)O_(6)=1, Al_(2)(SO_(4))_(3)=5`.
Higher the value of .i. more is depression in F.P.
