What reagent could not be used to separate Br^- from CO₃^2- when added to an aqueous solution containing both? A)AgNO₃(aq) B)Ca(NO₃)₂(aq) C)Cu(NO₃)₂(aq) D)Fe(NO₃)₂(aq)

Question

AgNO3 would not be able to separate Br^- from CO₃^2- since both compounds are not Ag+ precipitants (they do not form insoluble Ag+ salts). The other reagents (Ca(NO3)2, Cu(NO3)2, Fe(NO3)3) might be able to precipitate one of the compounds, allowing for separation.
