Question

The solubility of AB(s) in a 1.000-M solution of C(aq) is found to be 0.121 M. What is the Ksp of AB?
help please
The generic metal A forms an insoluble salt ABsolid and a complex AC5aqueous. The equilibrium concentrations in a solution of AC5 were found to be A is 0.100 M, C is 0.0320 M, and AC5 is 0.100 M. Determine the formation constant Kf of AC5
