Flame color caused by copper in the absence of halogens

Summary

[edit]
Description
Deutsch: Demonstration der Flammenfärbungen durch Erhitzen von Kupfer(II)-sulfat in der Flamme eines Bunsenbrenners. Durch Anregung wird sichtbares Licht Element-spezifischer Wellenlängen freigesetzt, was als Nachweis für Kupfer dienen kann. Wenn keine Halogene vorhanden sind, ist die Kupferflamme bläulich-grün statt blau.
English: Demonstration of flame colors used in the flame test by heating copper(II) sulfate in a Bunsen burner flame. Excitation of electrons causes release of electromagnetic radiation whose wavelengths are element-specific. In some cases, these wavelengths fall into the visible spectrum, making them useful as a test for certain elements, in this case copper. If no halogens are present, the copper flame is a bluish green rather than blue.
