What reagent could be used to separate Br^- from CH₃CO₂^-when added to an aqueous solution containing both? A)AgNO₃(aq) B)Ba(OH)₂(aq) C)CuSO₄(aq) D)NaI ₍_aq₎

Question

Quizplus · Accepted Answer

AgNO3 can selectively precipitate Br- ions as AgBr, while leaving the other ion in solution. This allows for easy separation of the two ions. The other reagents listed are not selective enough to only precipitate one ion and would not provide effective separation.
