Study Notes
- This set of flashcards details tests for identifying various metal ions and anions, focusing on flame tests and precipitate formation.
Flame Tests for Metal Ions
- Lithium ions (Li+) produce a red flame.
- Sodium ions (Na+) produce a yellow flame.
- Potassium ions (K+) produce a lilac flame.
- Calcium ions (Ca2+) produce an orange-red flame.
- Copper ions (Cu2+) produce a blue-green flame.
Reaction with Sodium Hydroxide
- Aluminium ions (Al3+) form a white precipitate that dissolves in excess sodium hydroxide solution.
- Calcium ions (Ca2+) form a white precipitate that does not change in excess sodium hydroxide solution.
- Copper ions (Cu2+) form a blue precipitate.
- Iron(II) ions (Fe2+) form a green precipitate.
- Iron(III) ions (Fe3+) form a brown precipitate.
Tests for Anions
- Ammonium ions produce ammonia gas, identified by turning damp red litmus paper blue.
- Carbonate ions produce carbon dioxide gas, identified by turning limewater milky.
- Sulfate ions form a white precipitate when present.
- Chloride ions (Cl-) form a white precipitate.
- Bromide ions (Br-) form a cream precipitate.
- Iodide ions (I-) form a yellow precipitate.
