18. Aqueous Equilibrium / Precipitation: Ksp vs Q / Problem 2

A solution of two silver salts contains 0.0111 M Cl- and 0.0125 M Br-. Upon addition of a very dilute solution of silver nitrate (AgNO3), a precipitate is formed.

A. Identify the precipitate as AgCl or AgBr.

B. Calculate the minimum concentration of Ag+ at which the precipitate begins to form.

Ksp(AgCl) = 1.8×10–10
Ksp(AgBr) = 5.0×10–13
