| 9724967729 | Test for Carbonate anion | Add dilute acid- result will be effervescence as Carbon Dioxide is produced. | 0 | |
| 9725410813 | Test for Chloride (in solution) anion | Acidify with dilute nitric acid, then add Aqueous Silver Nitrate. White precipitate is produced. | 1 | |
| 9731367748 | Test for Bromide (in solution) anion | Acidify with dilute nitric acid, then add Aqueous Silver Nitrate. Cream precipitate is produced. | 2 | |
| 9731372297 | Test for Iodine (in solution) anion | Acidify with dilute nitric acid, then add Aqueous Silver Nitrate. Yellow precipitate is produced. | 3 | |
| 9731374272 | Test for Nitrate (in solution) anion | Add aqueous sodium hydroxide, then aluminium foil; warm carefully. Ammonia is produced. | 4 | |
| 9731394509 | Test for Sulfate (in solution) anion | Acidify, then add Aqueous Barium Nitrate. White precipitate produced. | 5 | |
| 9731406887 | Test for Sulfite (in solution) anion | Add dilute hydrochloric acid, warm gently and test for the presence of Sulfur Dioxide. Sulfur Dioxide produced will turn acidified aqueous Potassium Manganate(VII) from purple to colourless. | 6 | |
