Colors of Elements in a Flame - Cobalt(II) Chloride

Cobalt(II) Chloride

No color is imparted to the flame by cobalt(II) chloride, but a large number of incandescent flashes shoot out with the stream of burning gas. Since these are white, they contain all colors of the visible spectrum, not the characteristic line spectrum of cobalt. A few tinges of yellow-orange sodium color appear as a consequence of traces of sodium impurity in the cobalt(II) chloride solution.
