Question

A saturated solution prepared by dissolving Ag2CO3 in water has [Ag+]=2.56× 10-4M. Hence, its Ksp is (A)  8.4× 10-12  (B)  1.68× 10-13  (C)  6.6× 10-8  (D)  1.6× 10-2

Ag2CO3leftharpoons 2Ag++CO32- [Ag+]=2.56× .0-4M [CO32-]=([Ag+]/2)=1.28× 10-4M Ksp=[Ag+]2[CO32-] =(2.56 × 10-4)2(128× 10-4) =8.4× 10-12

Q. A saturated solution prepared by dissolving $A g_{2} C O_{3}$ in water has $[A g^{+}] = 2.56 \times 10^{- 4} M .$ Hence, its $K_{s p}$ is

$8.4 \times 10^{- 12}$

$1.68 \times 10^{- 13}$

$6.6 \times 10^{- 8}$

$1.6 \times 10^{- 2}$

$A g_{2} C O_{3} ⇌ 2 A g^{+} + C O_{3}^{2 -}$ $[A g^{+}] = 2.56 \times .0^{- 4} M$ $[C O_{3}^{2 -}] = \frac{[ A g ^{+} ]}{2} = 1.28 \times 10^{- 4} M$ $K_{s p} = [A g^{+}]^{2} [C O_{3}^{2 -}]$ $= (2.56 \times 10^{- 4})^{2} (128 \times 10^{- 4})$ $= 8.4 \times 10^{- 12}$
