- Saw dust contains compounds of carbon Hydrogen and oxygen.
Procedure:
- Some saw dust is heated in an evaporating dish and some few drops of concentrated nitric (V) acid on it (this is done in a fume cupboard)
Observation:
- A violent reaction occurs, the saw dust catches fire easily and a lot of brown fumes of nitrogen (IV) oxide given off.
- Nitric (V) acid oxidizes the compounds in saw dust to CO2 and water; and itself it is reduced to nitrogen (IV) oxide and water.
