Answers
Answer:
Plunge the red hot tube into a china dish containing distilled water. Crush the contents with a glass rod and heat to boiling point. Stop heating and remove the insoluble matter by filtration. The filtrate is called Lassaigne's Extract.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.
