- Testing for ions
- Positive ions
- Flame test
- Lithium Ions
- Turns the flame a Crimson red
- Sodium Ions
- Turns the flame yellow
- Potassium ions
- Turns the flame a lilac/purple colour
- Copper ions
- Turns the flame green
- Calcium ions
- Turns the flame an orange/deep red
- Lithium Ions
- Adding Sodium Hydroxide
- Copper ions
- When added a blue precipitate is produced
- Calcium ions
- White precipitate that does not dissolve when more sodium hydroxide is added
- Magnesium ions
- White precipitate formed that does not dissolve when more sodium hydroxide is added
- Aluminium ions
- White precipitate forms and it dissolves when more sodium hydroxide is added
- Iron (II) ions
- A green precipitate formed
- Iron (II) ions
- A brown precipitate formed
- Copper ions
- Flame test
- Negative ions
- Add dilute acid test (Carbonate ions test)
- Carbonate ions
- Bubbles of gas given off and when the gas is passed through lime water it turns cloudy so Carbon dioxide is produced
- Only works for Carbonate ions so shows no reaction for...
- Bromide ions
- Sulfate ions
- Chloride ions
- Iodide ions
- Carbonate ions
- Add Barium chloride with hydrochloric acid ( Sulfate ion test)
- Sulfate ions
- A white precipitate is formed
- Only works for sulphate ions so shows no reaction for ...
- Chloride ions
- Bromide ions
- Iodide ions
- Carbonate ions - they do not react but give off bubbles of gas when acid is added
- Sulfate ions
- Add silver nitrate with nitric acid (Halide ion test)
- Only works for halide ions so now reaction for ...
- Carbonate ions do not react but give off bubbles of gas when acid is added

- White precipitate is formed
- Bromide ions
- A cream precipitate is formed
- Iodide ions
- yellow precipitate is formed
