The generic metal A forms an insoluble salt AB(s) and a complex AC5(aq). The equilibrium concentrations in a solution of AC5 were found to be [A] = 0.100 M, [C] = 0.0260 M, and [AC5] = 0.100 M. Determine the formation constant, Kf, of AC5. Kf=? The solubility of AB(s) in a 1.000-M solution of C(aq) is found to be 0.152 M. What is the Ksp of AB? Ksp=?
