Question

0.1 M solution of which of the following compounds will have the lowest freezing point? (A) FeSO 4 ⋅( NH 4)2 SO 4 ⋅ 6 H 2 O (B) [.CrCl2(.NH3.)].Cl (C) K 3[ Fe ( CN )6] (D) [ Co ( Cl )( NH 3)5] Cl 2

FeSO 4 ⋅( NH 4)2 SO 4 ⋅ 6 H 2 O (Mohr's Salt) is an example of double salt and have maximum number of ions in the solution, so it will have least freezing point.

$F e S O_{4} \cdot (N H_{4})_{2} S O_{4} \cdot 6 H_{2} O$

$[C r C l_{2} (N H_{3})] Cl$

$K_{3} [F e (CN)_{6}]$

$[C o (Cl) (N H_{3})_{5}] C l_{2}$
