Flashcards
Testing for ions
Cards in this deck (10)
- 1Dilute nitric acid is added followed by some silver nitrate solution. A cream precipitate forms.Bromide ions.
- 2Sodium hydroxide is added followed by aluminium powder or foil. The gas given off has a characteristic choking smell and turns red litmus paper blue.Nitrate ions.
- 3Dilute hydrochloric acid is added followed by some barium chloride solution. A white precipitate forms. Also, give the name of the precipitate.Sulphate ions (barium sulphate is the precipitate)
- 4Dilute nitric acid is added followed by some silver nitrate solution. A yellow precipitate forms.Iodide ions.
- 5A few drops of sodium hydroxide solution is added. The gas given off has a characteristic choking smell and turns red litmus paper blue. Also, give the name of the gas given off.Ammonium ions (ammonia is the gas)
- 6Dilute nitric acid is added followed by some silver nitrate solution. A white precipitate forms.Chloride ions.
- 7Dilute hydrochloric acid is added to the solution. The gas given off turns limewater cloudy/milky. Also, give the name of the gas given off.Carbonate ions (carbon dioxide is the gas)
- 8A liquid is blue in colour. What transitional metal ions are most likely to be present?Copper ions.
- 9A liquid is orange-brown in colour. What transitional metal ions are most likely to be present?Iron (III) ions.
- 10A liquid is green in colour. After being left to stand, it turns orange-brown in colour. What transitional metal ions are most likely to be present?Iron (II) ions.
