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 formula for solubility product constant

The solubility product constant \(K_{sp}\) for a solid \(A_xB_y(s)
ightleftharpoons xA^{y +}(aq)+yB^{x -}(aq)\) is given by \(K_{sp}=[A^{y +}]^x[B^{x -}]^y\). For the reaction \(AgCN(s)
ightleftharpoons Ag^{+}(aq)+CN^{-}(aq)\), the formula is \(K_{sp}=[Ag^{+}][CN^{-}]\). Solids (\(AgCN(s)\) in this case) do not appear in the \(K_{sp}\) expression as their activity is considered constant (equal to 1 in the context of solubility - product expressions).

Answer:

Numerator: \([Ag^{+}][CN^{-}]\), Denominator: \(1\) (since the activity of the solid \(AgCN(s)\) is \(1\) and not shown explicitly in the standard \(K_{sp}\) expression format for such problems, we can also just write \(K_{sp}=[Ag^{+}][CN^{-}]\))
