Hi, I have been set a question requiring the reagents to test for chloride and carbonate ions. They are from Silver Nitrate solution, Dilute nitric acid, Barium Chloride solution, Ammonium Hydroxide solution. Any help and the answers would be appreciated as I have no idea. Thanks

So, look at what the products would be if you reacted chloride or carbonate ions with each of those given reagents - what would you get?

For example, suppose you react chloride ions with silver nitrate and in a separate reaction, mix carbonate with silver nitrate? Would the products be distinguishable?

Well, for silver nitrate and chloride ions, you will see precipitation.

But not all precipitates are equal. Can you distinguish them?

I thought silver nitrate and chloride ions will form silver chloride, a white precipitate, and silver nitrate and carbonate ions will form silver carbonate, a yellow-greenish precipitate.

So you can use that reagent, for example, to distinguish between the two sets of ions.

@ stew1980: And now you can try out for other solutions. Searching for precipitates will help you.

You get Silver(I) Chloride as a white precipitate if you add aqueous Silver(I) Nitrate to a solution of chloride.

You get Barium Carbonate as a white precipitate if you add aqueous Barium Nitrate to a solution of carbonate.
