What does a small value of solubility product indicate about a salt?
Answer and explanation
Correct answer: The salt is sparingly soluble
For a given salt type and at a fixed temperature, Ksp is the equilibrium product of the concentrations of its ions in a saturated solution. A small Ksp generally means that only a small ionic concentration product is supported, so the salt is sparingly soluble. Exact comparisons require attention to stoichiometry: Ksp values of salts with different ion ratios cannot always be compared directly without calculation.
