The Preparation and Properties of Nitrogen(I) Oxide
In this classic demonstration, from the Royal Society of Chemistry, nitrogen (I) oxide is prepared by reacting sodium nitrate and ammonium sulphate. The nitrogen oxide is shown to re-light a glowing splint and be partially soluble in water; heating the gas with copper leaves nitrogen gas.
The resource provides a list of apparatus and chemicals needed for the experiment, together with teaching tips.
