1 Sodium azide is a rapidly acting, potentially deadly chemical that exists as an odorless white solid. 2  When it is mixed with water or an acid, sodium azide changes rapidly to a toxic gas with a pungent (sharp) odor. Breathing the gas that is formed from sodium azide causes the most harm, but ingesting (swallowing) sodium azide can be toxic as well. 2  The gas formed from sodium azide is most dangerous in enclosed places where the gas will be trapped. 3  The toxic gas quickly disperses in open spaces, making it less harmful outdoors.
Sodium amide, commonly called sodamide, is the inorganic compound with the formula NaNH 2.odium amide can be prepared by the reaction of sodium with ammonia gas, but it is usually prepared by the reaction in liquid ammonia using iron(III) nitrate as a catalyst. The reaction is fastest at the boiling point of the ammonia, c. â33 Â°C. An electride, [Na(NH 3) 6 ] + e â , is formed as an intermediate.
