Flame test - Wikipedia

2019-5-3 · A flame test is an analytic procedure used in chemistry to detect the presence of certain elements, primarily metal ions, based on each element''s characteristic emission spectrum. The color of flames in general also depends on temperature; see flame color.

Lab: Flame Test Flashcards | Quizlet

The value of this simple flame test is limited by interferences (e.g., the barium flame masks calcium, lithium, or strontium) and by aiguities (e.g., rubidium and cesium produce the same color as potassium). A colored glass is sometimes used to filter out light from one metal; for instance, blue cobalt glass filters out the yellow of sodium.

Metal Ion Flame Test Colours Chart | Compound Interest

2014-2-7 · This graphic looks at the colour of various metal and metalloid ions that occur during flame tests. Most people probably remeer doing this experiment in school chemistry lessons, if not with the full range of ions shown here, but for the uninitiated a brief explanation of the origin of the colours follows. Flame tests are utilised in chemistry to identify the metal ions in compounds.

Dyeing hair changes the color of the hair shaft. An experienced forensic examiner can immediately recognize the color as unnatural. In addition, the cuticle and cortex both take on the color of the dye. If an entire hair is recovered in an investigation, it is possible to estimate when the hair was last color-treated.

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.
