Description
Flame Coloration Set 1, NaCl, KCl, BaCl2, SrCl2, LiCl, CaCl2, UN-Nr. 3316
Set for the identification of minerals in the Bunsen burner flame through the characteristic flame colouring of the salts in the “flame test”.
During combustion, the metal or semi-metal ion contained in each chemical gives the flame a characteristic colour.
Application:
- Dip the magnesia rod into diluted hydrochloric acid (not included in the scope of delivery)
- Pick up some of the salt with the moistened magnesia rod
- Hold the end of the rod with the salt in the swooshing burner flame
Directions for use
If necessary, burn out the magnesia rods in the burner flame. The flame must be colourless. Otherwise there will still be residues of chemicals from previous experiments.
