Solution

The correct option is B (A) - (ii) ; (B) - (iv) ; (C) - (i); (D) - (iii)
$(A) F e (O H)_{3} \to F e^{+ 3} + 3 O H^{-}$
$F s p = (s) (3 s)^{3} = 27 s^{4}$

$(B) A g_{2} C r O_{4} \to 2 A g^{+} + C r O_{4}^{2 -}$
$K_{s p} = (2 s)^{2} (s) = 4 s^{3}$

$(C) C H_{3} O O A g \to C H_{3} O O^{-} + A g^{+}$
$K_{s p} = (s) (s) = s^{2}$

$(D) C a_{3} (P O_{4})_{2} \to 3 C a^{+ 2} + 2 P O_{4}^{3 -}$
$K_{s p} = (3 s)^{2} (2 s)^{2}$
$= 108 s^{5}$

$(A) - (i i), (B) - (i v), (C) - (i), (D) - (i i i)$
