Solubility product and common ion effect

Dissolve AgCl in water or in NaCl solution and see how the common Cl⁻ ion lowers its solubility.

Open the simulation

What to notice

Adding Cl⁻ from NaCl shifts the equilibrium left, so much less AgCl dissolves.

Key relation

AgCl ⇌ Ag⁺ + Cl⁻ ; K_sp = [Ag⁺][Cl⁻] = 1.8 × 10⁻¹⁰ (298 K)

Try this

Compare the solubility of AgCl in pure water and in 0.01 M NaCl.

What you can change

• NaCl concentration (log₁₀ M): -7 to -1

More in Equilibrium

• Buffer solutions (Henderson equation)
• Le Chatelier’s principle (Haber process)
• pH of acids and bases
