How Flame Test Colors Are Produced

The flame test is an analytical chemistry method used to help identify metal ions. While it's a useful qualitative analysis test—and a lot of fun to perform—it can't be used to identify all metals because not all metal ions yield flame colors. Also, some metal ions display colors that are similar to each other making it hard to tell them apart.

Flame Tests - Chemistry LibreTexts

Not all metal ions give flame colors. For Group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got. For other metals, there are usually other easy methods that are more reliable - but the flame test can give a useful hint as to where to look.

How to Do a Flame Test for Qualitative Analysis

The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of a Bunsen burner. The heat of the flame excites the electrons of the metals ions, causing them to emit visible light. Every element has a signature emission spectrum that can be used to differentiate between one element and another.

Flame Tests - Mineral

Table of Flame Colorations and Emission Spectra. This table of flame coloration is modified from the book "Determinative Mineralogy and Blowpipe Analysis" by Brush & Penfield, 1906. The colors are best observed by heating the sample on a loop of platinum wire moistened with HCl.
