What reagent could not be used to separate Cl^- from S^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)₃(aq)

AgNO3 would precipitate Cl^- as AgCl, but it would not precipitate S^2- because it does not form a precipitate with AgNO3. The other options (B, C, and D) contain metal ions that would also precipitate S^2- as insoluble salts, so they are not the best choice.
