Which of the following compounds has the lowest solubility in mol/L in water at 25°C? A)Ag₃PO₄K_sp = 1.8 $\times$10^-¹⁸ B)Sn(OH)₂K_sp = 3 $\times$10^-²⁷ C)CdS K_sp = 1.0 $\times$ 10^-²⁸ D)CaSO₄K_sp = 6.1 $\times$10^-⁵ E)Al(OH)₃K_sp = 2 $\times$ 10^-³³

Question

Quizplus · Accepted Answer

The compound with the lowest solubility will have the smallest value for its solubility product constant (Ksp). As Ksp is directly proportional to the solubility of a compound, the smaller its value, the lower the solubility. Among the options given, CdS has the smallest Ksp value, which indicates the lowest solubility in water at 25°C.
