Why do scientists use flame tests?

Answer 1

To Determine the emission spectrum of a sample

Answer 2

Scientists use flame tests to identify the type of metal ions present in a sample. When the sample is heated in a flame, it emits distinct colors of light based on the metal ion present. By observing and comparing the colors produced, scientists can determine the identity of the metal ion in the sample.

Answer 3

It is a quick and easy way of telling what is in the substance. I.e. If you think Chem A has metal B in it, and you know metal B gives a purple flame, and you burn Chem A, and the flames purple, you have a good idea you are correct.

Its not a foolproof test so dont rely on it.

Answer 4

Flame Tests are confirmatory tests for certain specific elements, most of which are metals. Scientists use these tests because these tests give a perfect idea of the presence of a particular element by the colour of the flame observed.

Take for instance an unknown compound is given wherein one is asked to determine the basic radical (the metal; if present). A glass rod is dipped in concentrated HCl and then touched to the salt. The mixture is then put to flame. If the flame imparts a color of golden yellow, it is sodium; if it imparts brick red color, it is calcium.

Nevertheless, all elements do not exhibit flame tests, but the ones which exhibit the test give a confirmation of the presence of the concerned metal.

Answer 5

they use flame tests to to find out a name of a chemical that they are unsure of. they can find this by out by using a special chemical key. they also see what the colour of the flame turns when the chemical burns to help them use the key. i hope that helps

Answer 6

to differentiate between the elements (even if they are in compounds) as it is a specific property e.g, sodium has golden yellow color

Answer 8

Different metals have different colors in the flame; the flame test is a method of qualitative analytical chemistry.

Answer 9

it is a method to identify some substances. In its more sophisticated form the color of the flame is analyzed thru spectroscopy to get a very accurate knowledge of the makeup of a substance.
