For the detection of sulfur in an organic compound, Lassaigne’s ...
Test is commonly used. In this test, the organic compound is first mixed with sodium metal and heated. The mixture is then extracted with water, and the resulting solution is treated with hydrochloric acid to precipitate any sulfur present as silver sulfide (Ag2S). The silver sulfide precipitate is black in color, confirming the presence of sulfur in the organic compound.
