Question

Adding NaCl to a solution of AgCl (Ksp = 1.8×10⁻¹⁰) will:
  1. A
    Increase solubility of AgCl
  2. B
    Decrease solubility of AgCl
    Correct
  3. C
    No effect on AgCl solubility
  4. D
    Increase Ksp

Correct answer

Decrease solubility of AgCl

Explanation

Common ion effect: added Cl⁻ from NaCl suppresses AgCl dissolution (shifts equilibrium left → less AgCl dissolves). Ksp remains constant.
