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)

AgNO3 can selectively react with Br- to form a precipitate of AgBr. This allows for the separation of Br^- from CH₃CO₂^- in aqueous solution. Ba(OH)2 would not be effective as it would precipitate all ions containing ₂. CuSO4 would not be effective as neither Br- nor CO₂ are able to react with it. NaI could potentially react with both Br- and CO₂, but AgNO3 is a more reliable and selective option.
