The solubility of salts that contain the conjugates of weak acids increase in acidic solution. Given the reaction of CuCN (Ksp = 3.47 x 10⁻²⁰) with an acid in the form H₃O⁺ shown below, find the equilibrium constant for this reaction given that Ka HCN = 4.9 × 10⁻¹⁰. CuCN(s) + H₃O⁺(aq) ⇌ Cu⁺(aq) + HCN(aq) + H₂O(l)
