Little substance is dissolved in concentrated HCl on a watch glass, then dip the Ni-Cr wire which has a net and then burn it over the flame of oxidation, observe the flame color arising:
Red Karmin: Sr
Red Yellow: Ca
Purple: K (use glass Cobalt)
Green: Cu, Borat
Green Yellow: Ba
Blue Gray: Mg, Pb, As, Sn, Sb and Fi
2. Beilstein flame reaction
Copper wire which has a clean, dipijarkan over the flame until the flame of oxidation of the green is gone, dip it in substance and perikasalah flame going. If there is halogen, then there is a green flame.
3. Nyala reaction to Borat
In a porcelain cup, a little solid concentrated sulfuric acid is added, then a few drops of methanol, and kindle in the dark. If there are borates, will form a green flame.
