Key Stage 4
Meaning
Flame Tests are an experiment which can be used to identify the metal elements in a metal compound.
About Flame Tests
- When a metal compound is heated by a flame it causes the electrons in the metal to gain energy and move to a higher Electron Orbital. When they electrons fall back down to their lower Electron Orbital some light is given off. Each metal produces different colours of light.
Metal Ion | Flame Colour |
Lithium | Red |
Sodium | Orange |
Potassium | Lilac (Purple) |
Calcium | Orange-red |
Barium | Brown-green |
Copper | Green-blue |
Lead | Blue |
Method
- Dip the end of an Inoculation Loop into concentrated Hydrochloric Acid.
- Place the end of the Inoculation Loop into the powdered metal compound.
- Hold the end of the Inoculation Loop in a roaring blue Bunsen Burner flame.
- Observe and record the colour of the flame.
