 Sodium fusion test

Conversion of suitable covalently bound nitrogen, sulfur or halogens into species detectable in an aqueous extract. Incomplete conversion and interfering species require controls.

The Sodium Fusion Test, also known as the Lassaigne's Test, is a qualitative analytical technique used primarily in organic chemistry to detect the presence of certain elements in organic compounds, specifically nitrogen, sulfur, and halogens (such as chlorine, bromine, and iodine). ### Procedure: 1. **Fusion with Sodium**: A small amount of the organic compound is mixed with an excess of metallic sodium in a dry test tube and heated strongly.
