When HCI gas is passed through saturated solution of rock salt, the solubility of NaCl:
Correct answer: B. Decreases.
- A. Increases.
- B. Decreases.
- C. May increase or decrease.
- D. None of these.
Explanation
NaCl⇌Na++ CI-HCI⇌H++CI-Due to common ion effect solubility of NaCl decreases.

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.
