An aqueous solution contains bromide ions and nitrate ions. What compound could be added which would separate the bromide and nitrate ions through by precipitating one out but not the other? There are other cations in solution in addition to those two anions but you do not need to know their identity in order to answer this question. AgNO3 CuSO4 NaI NaOH

A homogeneous solution contains copper(II) ions (Cu2+), silver ions (Ag+), and potassium ions (K+). You have sodium bromide (NaBr) and sodium sulfide (Na2S) available to use. What should you add and in what order to separate the three metal ions? Ksp (sulfides) CuS 6.0 10^-37 Ag2S 6.0 10^-51 K2S soluble Ksp (bromides) CuBr2 soluble AgBr 7.7 10^-13 KBr soluble Periodic Table and Datasheet 1. Add NaBr; AgBr precipitates out and can be separated. 2. Add Na2S; CuS precipitates out and can be separated; leaving K+(aq). 1. Add Na2S; CuS precipitates out and can be separated. 2. Add NaBr; AgBr precipitates out and can be separated; leaving K+(aq). 1. Add NaBr; CuBr2 precipitates out and can be separated. 2. Add Na2S; Ag2S precipitates out and can be separated; leaving K+(aq). 1. Add Na2S; K2S precipitates out and can be separated. 2. Add NaBr; CuBr2 precipitates out and can be separated; leaving Ag+(aq).
