Flame Test Colors and Procedure (Chemistry)
There are several ways of performing the flame test. Dissolve the sample in water or another solvent, soak a wooden splint in the liquid, and let it dry. Dip a Nichrome wire into a solid or liquid sample. Make a paste of a solid sample with hydrochloric acid (HCl) and dip a splint or wire into the paste. Dip a cotton swab into the sample.

Flame Test—Student Laboratory Kit. Price: $39.00. In Stock [332 pcs available]. To view alternative items others have purchased, please see "Suggested Products" below. With the Flame Tests Chemistry Laboratory Kit, students observe the characteristic color of light emitted by metallic salts when placed in a flame.
Flame tests (the wooden splint method)
Watch this experiment in our practical video Identifying ions. Lead salts are best avoided. They carry an extra risk, and the flame test result is not that impressive. The chlorides of metals give the best results, but other salts, such as sulfates, also work. Nitrates are best avoided in order to avoid production of toxic nitrogen oxides.
Flame tests using metal salts
Method 2: Take the nichrome or platinum wire and create a small loop at the end by bending the wire. Light the Bunsen burner. Turn the collar on the Bunsen burner so that you have an invisible or pale blue flame. Burn the loop end of the wire to remove any dust. Dip the loop into the lithium salt solution.
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.
Classroom Resources
Additional safety information: The Rainbow Demonstration (or Rainbow Flame Demonstration) is an activity popularly conducted in chemistry classrooms. The purpose is to demonstrate to students the variety of colors produced when different metals or metallic salts meet a flame. This procedure is an updated version of the traditional one.
Flame colours: a demonstration
Demonstration. This demonstration experiment can be used to show the flame colours given by alkali metal, alkaline earth metal, and other metal, salts. This is a spectacular version of the 'flame tests' experiment that can be used with chemists and non-chemists alike. It can be extended as an introduction to atomic spectra for post-16 students.
Flame test
A flame test is relatively quick test for the presence of some elements in a sample. The technique is archaic and of questionable reliability, but once was a component of qualitative inorganic analysis.The phenomenon is related to pyrotechnics and atomic emission spectroscopy. [1] The color of the flames is understood through the principles of atomic electron transition and photoemission ...
How to Do the Flame Test
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. If a wooden splint is used, it's necessary to wave the sample through the flame to avoid setting the wood on fire. The color of the flame is compared against ...
Flame Test
The flame test is one of the most commonly used analytical processes in chemistry. It is widely used to detect and analyze the presence of certain elements in the given salt or compound. Primarily, the flame test detects the presence of metal ions in a compound, and as ions of each element have a specific characteristic based in their emission ...
PDF Flame Tests for Metals
Use scoopulas supplied with each salt to place pea-sized samples of each metal salt into a test tube. Place the tubes in the test-tube rack. Pour about 15 mL of 6M HCl into a clean, labeled 50-mL beaker. Dip the wire loop into the 6M HCl and then heat it in. the hot flame of a gas burner, as shown in Figure 6.1a.
Flame Tests
Flame tests can be conducted in several ways, either by using solid compounds or solutions of compounds being tested. Either way, the aim of the lesson is the same. Students burn a tiny sample of a solution or solid compound using a flame test loop. The loops can be made of twisted nichrome wire fixed into the end of a suitable handle, usually ...
Spot tests: past and present
Microchemistry, i.e., the chemistry performed at the scale of a microgram or less, has its roots in the late eighteenth and early nineteenth centuries. In the first half of the twentieth century a wide range of spot tests have been developed. For didactic reasons, they are still part of the curriculum of chemistry students. However, they are even highly important for applied analyses in ...

Abstract A method for measuring local flame temperatures using a spectral-ratio pyrometer and a tomographic system based on this method are described. The theoretical substantiation of the proposed measurement method is given. A block diagram of the system containing four measuring mirrors and one multiplexing mirror is shown. The results of the computer simulation are presented, with which it ...

As a popular meta-heuristic algorithm, the Moth-Flame Optimization (MFO) algorithm has garnered significant interest owing to its high flexibility and straightforward implementation. However, when addressing engineering constraint problems with specific parameters, MFO also exhibits limitations such as fast convergence and a tendency to converge to local optima. In order to address these ...
