Solution

The correct option is D $5.3 \times 10^{- 12}$
$A g_{2} C_{2} O_{4} (S) ⇌ 2 A g^{+} (a q) + C_{2} O_{4}^{2 -} (a q)$
$K_{S P} = [A g^{+}]^{2} [C_{2} O_{4}^{2 -}]$
$[A g^{+}] = 2.2 \times 10^{- 4} M$
$∴ [C_{2} O_{4}^{2 -}] = \frac{2.2 \times 10^{- 4}}{2} M = 1.1 \times 10^{- 4} M$
$∴ K_{S P} = (2.2 \times 10^{- 4})^{2} (1.1 \times 10^{- 4})$
$= 5.324 \times 10^{- 12}$
