Azide salts can decompose with release of large volumes of nitrogen gas as discussed under Applications.

Protonation of azide salts gives toxic hydrazoic acid in the presence of strong acids:

H+ + N3− → HN3

Azide salts may react with heavy metals or heavy metal compounds to give the corresponding azides, which are more shock sensitive than sodium azide alone. They decompose with sodium nitrite when acidified. This is a method of destroying residual azides, prior to disposal.

2 NaN3 + 2 HNO2 → 3 N2 + 2 NO + 2 NaOH

Many inorganic covalent azides, e.g. chlorine, bromine, and iodine azides, have been described.

The azide anion behaves as a nucleophile; it undergoes nucleophilic substitution for both aliphatic and aromatic systems. It reacts with epoxides, causing a ring-opening; it undergoes Michael-like conjugate addition to 1,4-unsaturated carbonyl compounds.

Azides can be used as precursors of the metal nitrido complexes. Azide complexes thus is induced to release N2, generating a metal complex in unusual oxidation states (see high-valent iron).
