Question

construct the expression for ksp for solid agcn in aqueous solution. agcn(s) ⇌ ag⁺(aq) + cn⁻(aq) based on your knowledge of how the solid will dissociate in aqueous solution, construct the expression for the solubility constant, ksp. each reaction participant must be represented by one tile. ksp =

Explanation:

Step1: Recall the solubility product constant formula

For a general dissolution reaction \(AB(s)
ightleftharpoons A^{n +}(aq)+B^{m -}(aq)\), the solubility product constant \(K_{sp}=[A^{n +}]^m[B^{m -}]^n\). In the case of \(AgCN(s)
ightleftharpoons Ag^{+}(aq)+CN^{-}(aq)\), the stoichiometric coefficients of \(Ag^{+}\) and \(CN^{-}\) are both \(1\).

Step2: Construct the \(K_{sp}\) expression

According to the formula \(K_{sp}=[\text{products}] / [\text{reactants}]\), but for solids (like \(AgCN(s)\)), their activities (or concentrations in the context of \(K_{sp}\) expressions) are taken as \(1\) (not included in the \(K_{sp}\) expression). So \(K_{sp}=[Ag^{+}][CN^{-}]/1\).

Answer:

\(K_{sp}=\frac{[Ag^{+}][CN^{-}]}{1}\)
