STANDARD Chemistry Solubility Product MCQ Question
The solubility product of AgCl is 1.8 × 10⁻¹⁰. Precipitation of AgCl will occur by mixing which of the following solutions in equal volumes?
10⁻⁸ M Ag⁺ and 10⁻⁸ M Cl⁻ ions
10⁻³ M Ag⁺ and 10⁻³ M Cl⁻ ions
10⁻⁶ M Ag⁺ and 10⁻⁶ M Cl⁻ ions
10⁻¹⁰ M Ag⁺ and 10⁻¹⁰ M Cl⁻ ions
Correct Answer
Detailed Explanation
For precipitation, the ionic product must be greater than the solubility product. Mixing 10⁻³ M Ag⁺ and 10⁻³ M Cl⁻ ions results in an ionic product of 10⁻⁶, which is greater than 1.8 × 10⁻¹⁰.
