sodium metal is highly reactive, has low melting point and near unversal solubility of its compounds. the elements like N, X, S cannot be detected in organic compounds due to their stable covalent nature. Hence, these are converted into ionic forms by simply fusing with sodium metal and performing simple tests.
it is done to test the presence of nitrogen , halogens and othr elements
because of its electropositive nature. it is cheap also. although potassium can be used but it is costly... and lithium is less electropositive... Lassaigne's test is a test for the detection of halogens, nitrogen and sulphur in an organic compound. These elements are covalently bonded to the organic compounds. In order to detect them, these have to be converted into their ionic forms. This is done by fusing the organic compound with sodium metal. The ionic compounds formed during the fusion are extracted in aqueous solution and can be detected by simple chemical tests. The extract is called sodium fusion extract or Lassaigne's extract.
Sodium carbonate is added with the purpose to increase the pH of the solution.

Electrochemistry is the test that can be carried to confirm the presence of sodium gas in electrolysis.

The purpose of the bile esculen azide agar is to inhibit the growth of gram-positive organisms.
When an organic compound is heated strongly with sodium, any halogens, nitrogen, and sulfur will be converted into inorganic sodium salts such as sodium halide (for halides), sodium cyanide(for nitrogen), sodium sulfide (for sulfur), and sodium thiocyanate (for sulfur and nitrogen).The nitrogen is confirmed with ferrous sulfate i.e. iron sulfate.

Bright yellow :: This is the sodium ions. Any sodium compound will give a flame test colour of yellow/
assay test of sodium acid citrate
No, sodium chloride is a very stable compound
In test reactors.
Determining sodium or chlorine by analytical chemistry methods. In the flame test the color is yellow (from sodium radiation).
Nuclear fusion is not used for any purpose at present, it is still in the experimental phase
