A saturated solution of a sparingly soluble salt is one in which
Correct answer: B. the dissolved ions are in equilibrium with the undissolved solid
- A. no more solid can be added to the container
- B. the dissolved ions are in equilibrium with the undissolved solid
- C. the salt has completely dissolved
- D. the solubility product has been exceeded
Explanation
In a saturated solution ions leave the solid surface and return to it at the same rate, so the concentration of dissolved ions stays constant and equals the value fixed by Ksp. If the ionic product were pushed beyond Ksp the excess would precipitate until equilibrium was restored. Undissolved solid must be present for the equilibrium to exist at all.

The more specific you are, the faster it gets fixed. A source beats an opinion.

About Solubility Product
The solubility product constant, Ksp, represents the equilibrium concentrations of ions from a sparingly soluble salt, each raised to its stoichiometric power. Problems involve writing Ksp expressions, calculating molar solubility, applying the common-ion effect and predicting precipitation from the ionic product.
