A) \[0.05M\,N{{a}_{2}}C{{O}_{3}}\]
B) \[0.05\,M\,AgN{{O}_{3}}\]
C) pure water
D) \[0.05\,N\,N{{H}_{3}}\]
Correct Answer: D
Solution :
\[A{{g}_{2}}C{{O}_{3}}2\,A{{g}^{+}}CO_{3}^{2-}\]Due to the common ion effect, the solubility decreases, so the solubility of \[A{{g}_{2}}C{{O}_{3}}\]would be greatest in 1 L of \[\text{0}\text{.05 M N}{{\text{H}}_{\text{3}}}\]due to the absence of common ion either \[A{{g}^{+}}\]or\[CO_{3}^{2-}+A{{g}^{+}}\] form complex with \[\text{N}{{\text{H}}_{\text{3}}}\]\[A{{g}^{+}}+2N{{H}_{3}}\rightleftharpoons {{[Ag{{(N{{H}_{3}})}_{2}}]}^{+}}\]
