STANDARD Chemistry Common Ion Effect MCQ Question

Type: MCQ-numerical-Medium

What will be the solubility of AgCl in 0.05 M NaCl aqueous solution if solubility product of AgCl is 1.5 × 10⁻¹⁰?

A

3 × 10⁻⁹ mol L⁻¹

B

0.05 mol L⁻¹

C

1.5 × 10⁻⁵ mol L⁻¹

D

3 × 10⁹ mol L⁻¹

Correct Answer

Option A

Detailed Explanation

In the presence of 0.05 M Cl⁻ from NaCl, the solubility of Ag⁺ is reduced. Kₛₚ = [Ag⁺][Cl⁻] = 1.5 × 10⁻¹⁰, solving gives [Ag⁺] = 3 × 10⁻⁹ mol L⁻¹.
