question 41

Multiple Choice

An aqueous solution contains 0.010 M Br^- and 0.010 M I^-.If Ag⁺ is added until AgBr(s) just begins to precipitate,what are the concentrations of Ag⁺ and I^-? (K_sp of AgBr = 5.4 × 10^-13,K_sp of AgI = 8.5 × 10^-17)

• A) [Ag⁺] = 5.4 × 10^-11 M,[I^-] = 1.0 × 10^-2 M
• B) [Ag⁺] = 8.5 × 10^-15 M,[I^-] = 1.0 × 10^-2 M
• C) [Ag⁺] = 5.4 × 10^-11 M,[I^-] = 1.6 × 10^-6 M
• D) [Ag⁺] = 8.5 × 10^-15 M,[I^-] = 6.4 × 10¹ M
• E) [Ag⁺] = 8.5 × 10^-15 M,[I^-] = 1.6 × 10^-6 M
