Flame test of metal ions
WebAug 16, 2024 · The test is used to identify metal ions (and certain other ions) based on the characteristic emission spectrum of the elements. The test is performed by dipping a wire or wooden splint into a sample solution or coating it with the powdered metal salt. The color of a gas flame is observed as the sample is heated. WebFlame tests and chemical tests are used to detect and identify ions in samples. Instrumental methods of analysis are faster, and more accurate and sensitive than simple chemical tests....
