The solubility of Agl and Nal is less than in pure water because:
Correct answer: B. Of common ion effect
- A. Agl forms a complex with Nal
- B. Of common ion effect
- C. Solubility of Agl is less than Nal
- D. The temperature of solutions decreases
Explanation
Adding NaI into a solution of AgI decreases the solubility for AgI as both have a common ion I- so equilibrium moves towards the left side and ppt of AgI forms

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.
