Solution

The correct option is C $8.39 \times 10^{- 12}$
Given, $[A g^{+}] = 2.56 \times 10^{- 4}$
In saturated solution of $A g_{2} C O_{3} (s)$
the dissociation equation is given by
$A g_{2} C O_{3} (s) + H_{2} O ⇌ 2 A g^{+} (a q) + C O_{3}^{2 -} (a q)$
$K_{s p} = [A g^{+}]^{2} [C O_{3}^{2 -}]$
Also, $[C O_{3}^{2 -}] = \frac{1}{2} [A g^{+}]$
$[A g^{+}] = 2.56 \times 10^{- 4} M$
$∴ [C O_{3}^{2 -}] = 1.28 \times 10^{- 4} M$
So $K_{s p} = [A g^{+}]^{2} [C O_{3}^{2 -}] = (2.56 \times 10^{- 4})^{2} \times (1.28 \times 10^{- 4})$
$K_{s p} = 8.39 \times 10^{- 12}$
