The product of the concentrations of each ion in a saturated solution of a sparingly soluble salt at 298 K, raised to the power of their relative concentrations, is the:
Correct answer: A. Ksp
- A. Ksp
- B. Ka
- C. Kw
- D. Kb
Explanation
This is the definition of the solubility product constant (Ksp ). It represents the equilibrium constant for the dissolution of a sparingly soluble ionic compound into its constituent ions in a saturated solution.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
