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 directly proportional to the square root of its solubility product, so we need to find the salt with the largest square root of 1.0 × 10^-6. Option C has anionic charge of 3- and thus, it requires fewer cations for it to dissolve on water and therefore, will have the highest solubility among the given salts.
