A solution contains 0.1 M Cl– and 0.001 M CrO42–. If solid AgNO3 is gradually added to this solution which will precipitate first, AgCl or Ag2CrO4 ? Assume that the addition causes no change in volume. Given Ksp(AgCl)= 1.6 × 10–10 M2 and Ksp(Ag2CrO4) = 1.79 × 10–12 M3. What % of Cl– remains in solution when CrO42– starts precipitating ?
