What is the molar concentration of the cyanide ion (CN$^-$) in a saturated solution of AgCN buffered to pH = 6.125? (Assume complex formation is negligible under these conditions.) AgCN(s) \rightleftharpoons Ag^+(aq) + CN^-(aq) K_{sp} = 2.2 \times 10^{-16} HCN(aq) + H_2O(l) \rightleftharpoons H_3O^+(aq) + CN^-(aq) K_a = 6.2 \times 10^{-10}

Find the concentrations of Ag⁺, CN⁻, and HCN in a saturated solution of AgCN whose pH is somehow fixed at 9.00. Consider the following equilibria: AgCN(s) ⇔ Ag⁺ + CN⁻ Ksp = 2.2 x 10⁻¹⁶ CN⁻ + H2O ⇔ HCN(aq) + OH⁻ Kb = 1.6 x 10⁻⁵

CN-(aq) + H2O(l) ⇌ HCN(aq) + OH-(aq) Kb = 1.61 x 10^-5 If the pH of a solution of NaCN(aq) is 8.710, then the equilibrium concentration of CN-(aq), expressed in scientific notation, is a.bc × 10^-d mol/L. The values of a, b, c, and d are _____, _____, _____, and _____. Hint: Convert pH to pOH or concentration of [OH-]. You'll need an equilibrium equation. You can write your numbers next to each other (3.43x10^-6 -> 3436)
