Of the following anions, Br-, CO32-, Cl-, I-, NO3-, NO2-, PO43-, SO42-, SO32-, list those ions that meet the following criteria:
(1) Gives a precipitate with Ag+ ion that is insoluble in HNO3. Br-, Cl-, I-
(2) Is involved in an oxidation-reduction reaction as part of a confirmation reaction. Br-, Cl-, I-, NO3-
(3) Gives a precipitate with Ba2+ ion that is soluble in HNO3. CO32-, PO43-
(4) Evolves a gas when acid is needed. CO32-, NO3-, NO2-, SO32-
(5) Releases an odorous gas as a product. NO3-, NO2-,SO32-
(6) Does not produce a precipitate in any classification or confirmatory reaction described in this experiment. SO42-
Any help is greatly appreciated. I'm stumped on this one. Are these answers close?
Thanks in advance,
