Flame test for copper ions
WebA flame test is a qualitative analysis used by the chemist to identify the metal and metalloid ion in the sample. Not all metal ions emit colour when heated in the gas burner. A flame test is the simplest way of identifying the presence of group 1 metal ions in the compound. Webcolorful flames and different metal ions produce different colors and in a mixture of different ions, the flame test will only show the brighter/more visible flame of the metal ions so …
