Tests for anions 

tests for hallide ions using silver nitrate solution 

to test for chloride bromide and iodide ions add some dilute nitric acid  followed by a few drops of silver nitrate solution 

a chloride gives a white prcicpitation of silver chloride 

a bromide gives a cream precipitate of silver bromide 

an iodide gives a yellow precipitate of silver iodide 

test for carbonattes using hydrochloric acid 

first add some barium chloride solution if carbonate ions are present, this will produce a white precipitate of barium chloride
