The decrease in solubility of the salt in a solution that already contains an ion common to that salt Is known as:
Correct answer: C. Common ion effect
- A. Le Chatelier's principle
- B. Solubility Product
- C. Common ion effect
- D. Ksp
Explanation
The decrease in solubility of a salt in a solution that already contains an ion common to the salt is known as the common ion effect. This effect occurs because the presence of the common ion reduces the solubility of the salt by shifting the equilibrium towards the solid form.

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.
