Just a quiz to see if you understand how to test for anions.

?
How do you test for Chloride ions?
Dissolve in dilute nitric acid, then a white precipitate forms with silver nitrate solution. (The precipitate dissolves in dilute ammonia solution.)

How do you test for Bromide ions?
Dissolve in dilute nitric acid, then a cream precipitate forms with silver nitrate solution. (The precipitate is insoluble in dilute ammonia solution, but will dissolve in concentrated ammonia solution)
2 of 6
How do you test for Iodide ions?
Dissolve in dilute nitric acid, then a pale yellow precipitate forms with silver nitrate solution. (The precipitate is insoluble in dilute and concentrated ammonia solution)

How do you test for Sulfate ions?
Dissolve in dilute nitric acid, then a white precipitate forms with barium chloride solution.

How do you test for Nitrate ions?
Add sodium hydroxide solution and warm with powdered aluminium, then test the gas given off (ammonia) with damp red litmus paper, which turns blue.
