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.
The compounds of sodium are soluble that is why it is used.
Prussian test is a part of lassaigne test, since prussain test used for nitrogen detection while lassaigne used for detection of halogens sulphur and nitrogen in organic compounds
Light green tube, with sodium heparin.
Reagents of Osazone test are 1. Phenylhydrazine mixture consisting of phenyl-hydrazine and anhydrous sodium citrate 2. Orignal solution containing a carbohydrate
Sodium Polyacrylate is used in many different things. Examples would be such things as disposable diapers, laundry detergent, and fake snow, and when you go to the store and buy the amazing growing dinosaurs. Those are only some of the uses for Sodium Polyacrylate.

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.

Sodium is an elemental metal, so sodium is the only element in sodium.
To identify the presence of certain metal ions, such as sodium and caesium.
Sodium chloride is not dangerous only if it is used in reasonable quantities.
Sodium and water are HIGHLY reactive. It would only compound the problem.
Sodium sulfite is used to remove permanganate stains because it is the only thing that can remove it. This is because the sodium sulfite breaks down the permanganate.
Sodium hydrogen carbonate is used as an indicator of pH or as a test for the concentration of carbon dioxide. For the preparation of the solution see the link below.
Anhydrous sodium acetate is added to buffer the phenylhydrazine HCl so that it may function properly. Regards mawaisnawaz@hotmail.com
A hair test, won't say when you've used, only if you have used.
