The precipitation occurs if the ionic concentration is:
Correct answer: B. More than ksp
- A. Less than ksp
- B. More than ksp
- C. Equal to ksp
- D. Present in any amount
Explanation
Precipitation occurs when the ionic concentration in a solution exceeds the solubility product of the compound. The solubility product is a constant that represents the maximum concentration of ions that can exist in a saturated solution at a given temperature. If the ionic concentration exceeds this maximum value, the excess ions will come together and form a solid precipitate.

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.
