A prussian blue colouration indicates the presence of nitrogen in the compound. If nitrogen is present in the compound, the sodium extract would contain sodium cyanide formed during fusion.
Lassaigne's test is used for the detection of elements present in the organic compound with the help of analysis.
Explanation:
Detection of nitrogen is carried out with the help of lassaigne's extract.
To the small part of the extract add 2ml of freshly prepared ferrous sulphate and heat the mixture.
Add to this solution two or three drops of ferric chloride solution and this solution is acidified with conc.hydrochloric acid.
This test is also known as the sodium fusion test.
This solution is heated. Now add to it 2-3 drops of ferric chloride solution and acidify with cone, hydrochloric acid.
