SUMMARY
The discussion centers on the solubility of lead carbonate (PbCO3) and its dependence on pH levels, particularly in tap water with a pH around 7. The solubility product constant (Ksp) for PbCO3 is established as 1.8166 x 10^-7 M. It is emphasized that the presence of carbonates in tap water primarily exists as bicarbonate ions (HCO3-), which significantly affects the solubility calculations. The question posed regarding the correctness of the approach and values used in the calculations indicates a need for clarity on the application of Ksp in solubility problems.
