Sodium Fusion Extract -

 

A small piece of sodium metal is heated with an organic compound for 2-3 minutes.

- wherein

The red hot tube is plunged into the distilled water after filtering this solution. It is known as sodium fusion extract

 

 

Sodium extract of organic compound gives violet colour with sodium nitroprusside solution when it contains sulphur. Thiourea\Rightarrow NH_2CSNH_2 contains sulphur hence it will give brilliant violet colour when given treatments.
