?
Carbonates
Addition of a dilute acid e.g. dilute HCl will give off carbon dioxide, which turns limewater cloudy
1 of 5
Sulfates
Adding HCl and barium chloride forms the white precipitate barium sulfate.
2 of 5
Halides
Add nitric acid to prevent false results then add silver nitrate and a precipitate will form.
3 of 5
Ammonium compounds
Ammonia gas turns red litmus paper blue; ammonium ions will give off ammonia when reacted with NaOH
