Qualitative Analysis : test for anions (negative)

Carbonate

Test: Add dilute acid

Result: effervescence, carbon dioxide produced

Chloride (in solution)

Test: Acidify with dilute nitric acid, then add aqueous silver nitrate

Result: white ppt.

Bromide (in solution)

Test: Acidify with dilute nitric acid, then add aqueous silver nitrate

Result: cream ppt.

Iodide ( in solution)

Test: Acidify with dilute nitric acid, then add aqueous silver nitrate

Result: yellow ppt.

Nitrate (in solution)

Test: add aqueous sodium hydroxide then aluminium foil, warm carefully

Result: ammonia produced

Sulfate ( in solution)

Test: acidify, then add aqueous barium nitrate

Result: white ppt.

Sulfite

Test: add dilute HCL, warm gently and test for the presence of sulfur dioxide

Result: Sulfur dioxide produced will turn acidified aqueous potassium manganate (VII) from purple to colourless
