Quizplus · Accepted Answer

The solubility of a salt is inversely related to the value of its solubility product (Ksp). The higher the Ksp value, the lower the solubility. Therefore, the order of increasing molar solubility, from the least soluble (highest Ksp) to the most soluble (lowest Ksp), is as follows: CdS (8 × 10^-27) < BaSO4 (1 × 10^-10) < AgCl (8 × 10^-10) < BaCO3 (1 × 10^-9) < PbSO4 (1.8 × 10^-8).
