Method is commonly used. In this method, the organic compound is first heated with sodium metal to convert sulfur into sodium sulfide. The resulting mixture is then dissolved in water and acidified with dilute hydrochloric acid. This acidic solution is then treated with a few drops of sodium nitroprusside solution, which forms a violet coloration if sulfur is present. This coloration confirms the presence of sulfur in the organic compound.
