Solution
Correct Answer:
Both HCl and NaCl
The Common Ion Effect states that the addition of an ion already present in the equilibrium mixture will shift the equilibrium away from that ion.
- AgCl(s)⇌Ag+(aq)+Cl−(aq)
- HCl provides H+ and Cl− ions.
- NaCl provides Na+ and Cl− ions.
- In both cases, the concentration of Cl− (a common ion) increases. According to Le Chatelier's principle, the equilibrium shifts to the left, causing more AgCl to precipitate.
- Consequently, the solubility of AgCl decreases in both solutions.
This easy difficulty chemistry question is from the chapter equilibrium, covering the topic of common ion effect. It appeared in the 2025 exam.
