State the colour for the flame test of a Lithium Ion (Li+)
Crimson/red
State the colour for the flame test of a Sodium Ion (Na+)
Orange
State the colour for the flame test of a Potassium Ion (K+)
Lilac/Purple
State the colour for the flame test of a calcium ion (Ca2+)
red

Green
State the observation when a few drops of sodium hydroxide is added to iron (II) chloride
green precipitate/solid
State the observation when a few drops of sodium hydroxide is added to iron (III) chloride
brown precipitate/solid
State the observation when a few drops of sodium hydroxide is added to copper chloride
blue precipitate/solid
State the observation when a few drops of sodiurecipitate/solidm hydroxide is added to calcium chloride
white precipitate/solid
State the observation when a few drops of sodium hydroxide is added to magnesium chloride
white precipitate/solid
State the observation when a few drops of sodium hydroxide is added to aluminium chloride
white precipitate/solid
State the observation when an excess of sodium hydroxide is added to aluminium chloride
precipitate dissolves/disappears
Describe how to distinguish between calcium and magnesium ions
flame test
calcium ions give a red flame
Describe the test for carbonate ions
Add an acid
Bubbles
of carbon dioxide
which turns limewater cloudy
Describe the test for sulphate ions
Add barium chloride
makes a white precipitate (solid)
