Leаd iоns cаn be precipitаted frоm aqueоus solutions by the addition of aqueous bromide:               Pb2+ (aq) + 2 NaBr (aq)  →  PbBr2 (s) + 2 Na+ (aq)   Lead(II) bromide is virtually insoluble in water so that the reaction appears to go to completion. How many grams of NaBr must be added to 40.0 mL of 0.555 M Pb2+ solution to completely precipitate the lead(II) ion?     (If you wish, show your work for possible partial credit.)
