Vedclass · Answer

(A) The dissociation of $Ag_{2}CrO_{4}$ is given by: $Ag_{2}CrO_{4} ightleftharpoons 2 Ag^{+} + CrO_{4}^{2-}$.Let the solubility be $s$. Then $[Ag^{+}] = 2s$ and $[CrO_{4}^{2-}] = s$.The solubility product expression is $K_{sp} = [Ag^{+}]^{2} [CrO_{4}^{2-}]$.Substituting the values: $K_{sp} = (2s)^{2} (s) = 4s^{3}$.Given $K_{sp} = 32 	imes 10^{-12}$,we have $4s^{3} = 32 	imes 10^{-12}$.$s^{3} = 8 	imes 10^{-12}$.$s = (8 	imes 10^{-12})^{1/3} = 2 	imes 10^{-4} \ M$.Since $[CrO_{4}^{2-}] = s$,the concentration is $2 	imes 10^{-4} \ M$.

The solubility product of $Ag_{2}CrO_{4}$ is $32 \times 10^{-12}$. What is the concentration of $CrO_{4}^{2-}$ ions in that solution?
