SUMMARY
The maximum solubility of lead iodide (PbI2) is not divided by two because the dissolution of PbI2 in water does not yield two separate ions in a 1:1 ratio. Instead, PbI2 dissociates into one lead ion (Pb²⁺) and two iodide ions (I⁻), resulting in a total concentration that reflects this stoichiometry. The correct maximum solubility value is 0.000187M, which aligns with the stoichiometric calculations for PbI2 dissolution.
