Why do scientists use flame tests?

Answer 1

To Determine the emission spectrum of a sample

Answer 2

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 3

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 4

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 5

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 7

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

Answer 8

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.
