Which of the following salts,each of which has a solubility product equal to 1.0 × 10^-6,has the greatest molar solubility?

Question

Quizplus · Accepted Answer

The molar solubility of a salt is governed by its solubility product constant (Ksp). The higher the value of Ksp, the higher the molar solubility of the salt. Among the given options, all salts have the same Ksp value of 1.0×10^-6. However, higher charge on the counterion tends to decrease the molar solubility of the salt due to increased electrostatic interactions between the counterions and the oppositely charged ions of the salt. The counterions in option C have the lowest charge among all the options, making it the best choice with the greatest molar solubility.
