Solution

The correct option is D $K_{4} [F e (C N)_{6}]$
van't Hoff factor
$A l_{2} (S O_{4})_{3} \to 2 A l + 3 + 3 S O_{4}^{2 -}$
$i = 5$
option (a);
$K_{3} [F e (C N)_{6}] \to 3 K^{+} + [F e (C N)_{6}]^{3 -} i = 4$
option (b);
$K_{4} [F e (C N)_{6}] \to 4 K^{+} + [F e (C N)_{6}]^{4 -} i = 5$
option (c):
$A l (N O_{3})_{3} \to A l^{3 +} + 3 N O_{3}^{-} i = 4$
Option (d):
$K_{2} S O_{4} \to 2 K^{+} + S O_{4}^{2 -} i = 3$
Hence, Option (b) is correct
