What element is responsible for the green flame produced in the beilstein test?
The Beilstein test is a simple chemical test used to test for halides. A positive test result is indicated by a green flame which is caused by the formation of a copper halide. This test is not used often because of the possibility of generating highly toxic chloro-dioxins if the test material is a polychloroarene.
What compound are responsible for Beilstein test?
test for halogen
What compound is responsible for beilstein test?
halogen containing compound
What is the Beilstein test in chemistry?
The Beilstein test is a simple chemical test used in chemistry as a qualitative test for halides. It was developed by Friedrich Konrad Beilstein.[1] A copper wire is cleaned and heated in a Bunsen burner flame to form a coating of copper(II) oxide. It is then dipped in the sample to be tested and once again heated in a flame. A positive test is indicated by a green flame caused by the formation of a copper halide. This test is little used nowadays; one reason why it is not popular is that it is possible to generate the highly toxic chloro-dioxins if the test material is a polychloroarene.[2] An alternative wet test for halide is the sodium fusion test - this test converts organic material to inorganic salts include the sodium halide. Addition of silver nitrate solution causes any halides to precipitate as the respective silver halide. :)
After hydrolysis did sucrose give a positive test with fehlings test why orwhy not?
After hydrolysis sucrose did give a positive test. It reduces sugar that has hemiketal and hemiaetal in it.

Does phenol give a positive biuret test?
No. The Biuret test only gives a positive result if a peptide bond exists. Phenol doesn't have a peptide bond, so it will not give a positive test.
Does formalin give positive Fehling's solution test?
Formalin gives a positive Fehling's solution test.
Salicyclic acid gives a positive test with FeCl3?
why does salicylic acid give a positive test with FeCl3
Will benadryl give you a false positive breathalizer?
I have to do weekly breathalyzer test will Benadryl make me test positive
What are the chances of a false positive with a pregnancy test?
If the test is done properly, the chances to give false positive test are very slim indeed.
What is observed when phenols are used in Baeyers test?
Phenols give a positive test.
