Answer By exposing materials to a hot flame (from a Bunsen burner typically), the color of the flame can be used to identify the material. Certain elements give off a characteristic color when heated to high temperature. See the Related Links for "Wikipedia: flame test" to the bottom for the answer.

What are three examples of qualitative?
- test of chlorine in water - test of sodium in a mixture by flame test - test of hydrogen sulphide in a gas mixture
What color does sugar produce you n a flame test?
Flame of itself is yellow/white. This is white hot carbon particles. Carbon, per se, does not form ions and so cannot give a flame test colour.
What element burns green in flame test?
Chromium I don't know about Chrome, maybe, but Copper definitely does and is the most well known for doing so. So I would say Copper. Copper burns blue-green in a flame test. Thallium burns bright green.
What is a Bunsen burner?
A Bunsen Burner is a controlled gas-burning heat source (a "gas candle") that supplies direct heat or flame for scientific experiments and research. (The flame can be blocked by screens to reduce the deposition of soot on test tubes and beakers.)
What are Two kinds of flame?
the yellow/safety flame - thats the one that burns less the blue flame - burns THE ROARING FLAME - that one burns a lot and you can tell the difference from the blue flame because it makes a roaring sound
Is a flame test a qualitative or quantitative test?
The flame test in analytical chemistry is only qualitative.
How can you test strontium nitrate ammonium carbonate and potassium sulfate?
To test for strontium nitrate, you can perform a flame test which will produce a red flame color. For ammonium carbonate, it will release ammonia gas when heated and form a white precipitate when reacted with a sodium hydroxide solution. Potassium sulfate can be identified by its solubility in water, as it is highly soluble.
What color does Na-Cl burn in a flame test?
NaCl burns yellow in a flame test.
What is the flame test for aluminum?
When aluminum is subjected to a flame test, it does not produce a distinct color flame. This is because aluminum does not have any characteristic flame color associated with it, unlike other elements that produce specific colors when heated.
How do you know if something is copper for example a vase?
you need to do the flame test you need to do the flame test
How do you test for potassium ions?
Flame test
Does Copper Chloride produce a blue-green or Red flame?
Copper chloride typically produces a blue-green flame when burned due to the presence of copper ions in the compound. The green color is a characteristic emission caused by the excitation of electrons in the copper atoms.
Examples of constant variables in flame test?
The temperature of the flame.
Is the flame test a qualitative or quantitative test for the identity of an unknown?
just looking at the color of the flame --- qualitative
What was the flame test original use?
The flame test is used for the qualitative determination of some ions in solution.
What is the result with iron II chloride in the test flame?
Iron has a yellow-gold color in the flame test.
Which metal reacts with water and burns with a lilac flame?
Potassium has a violet color in the flame test.
