Question

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. 0360 M, and [AC5] = 0. 100 M. Determine the formation constant, Kf, of AC5. The solubility of AB(s) in a 1. 000-M solution of C(aq) is found to be 0. 131 M. What is the Ksp of AB?

Answer 1

The formation constant, Kf, of AC5 is approximately 2.78 x 10^7 M^-4. The Ksp of AB is approximately 2.22 x 10^-8.
