Step-by-step solution

The nitrogen present in the organic compound on fusion with sodium metal gives sodium cyanide ( NaCN ) soluble in water. This is converted into sodium ferrocyanide by the addition of sufficient quantity of ferrous sulphate. 6 NaCN   +   FeSO 4   →   Na 4 [ Fe ( CN ) 6 ] Sodium ferrocyanide   +   Na 2 SO 4 Ferric ions generated during the process react with ferrocyanide to form Prussian blue precipitate of ferric ferrocyanide. Na 4 [ Fe ( CN ) 6 ]   +   Fe 3 + &#160
