Which compound listed below has the greatest molar solubility in water? A)CdCO₃ B)Cd(OH)₂ C)AgI D)CaF₂ E)ZnCO₃

Question

Quizplus · Accepted Answer

CaF2 has the greatest molar solubility in water among the options given. This is because, compared to the other compounds listed, which are either sparingly soluble (such as AgI and CdCO3) or have very low solubility due to their strong ionic bonds and low solubility product constants (Ksp), calcium fluoride (CaF2), despite also being sparingly soluble, tends to have a slightly higher solubility than the other compounds mentioned. This is a relative comparison, as all the compounds are generally considered to have low solubility in water, but among them, CaF2 is expected to dissolve more than the others under the same conditions.
