Many salts of Pb2+ are sparingly soluble, and the difference in their solubility can be used to separate anions from solution.A solution is 0.0151 M in both Br– and SO42–. A 0.257 M solution of lead(II) nitrate is slowly added to it with a buret. The (pick one: Br^- or SO_4^2-) anion will precipitate from the solution first. (Ksp for PbBr2 = 6.60 ×× 10–6; Ksp for PbSO4 = 2.53 ×× 10–8) What is the concentration in the solution of the first anion when the second one starts to precipitate at 25°C? ___ M
