Question

Find the molar solubility of PbCO3 solid in a 1.50 M sodium oxalate solution (which provides the bidentate ox^2- ligand). The Ksp for PbCO3 is 7.4x10^-14 and the Kf for the [Pb (ox)2]^2- complex ion is 3.5x10^6.
What is the new K value for the combined solubility equilibrium and formation equilibrium?
