question 12

Multiple Choice

Assuming that the total volume does not change after 0.200 g of KCl is added to 1.0 L of a saturated aqueous solution of AgCl, calculate the number of moles of Ag⁺ ion in the solution after equilibrium has been reestablished. For AgCl, K_sp = 1.8 × 10^-10.

• A) 1.8 × 10^-10 mol Ag⁺
• B) 9.0 × 10^-10 mol Ag⁺
• C) 9.0 × 10^-9 mol Ag⁺
• D) 6.7 × 10^-8 mol Ag⁺
• E) 1.3 × 10^-5 mol Ag⁺
