Question Answer
Dilute nitric acid is added followed by some silver nitrate solution. A cream precipitate forms. Bromide ions.
Sodium 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.
Dilute 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)
Dilute nitric acid is added followed by some silver nitrate solution. A yellow precipitate forms. Iodide ions.
A 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)
Dilute nitric acid is added followed by some silver nitrate solution. A white precipitate forms. Chloride ions.
Dilute 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)
A liquid is blue in colour. What transitional metal ions are most likely to be present? Copper ions.
A liquid is orange-brown in colour. What transitional metal ions are most likely to be present? Iron (III) ions.
A 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.
