'''Copper(II) azide''' is a medium density [[explosive]] with the [[molecular formula]] [[Copper|Cu]]([[Nitrogen|N]]<sub>3</sub>)<sub>2</sub>.
'''Copper(II) azide''' is a medium density [[explosive]] with the [[molecular formula]] {{chem2|[[Copper|Cu]]([[Nitrogen|N]]3)2}}.


__TOC__
==Uses==
==Uses==
Copper azide is very [[explosive]] and can be used in [[pyrotechnics]].
Copper azide is very [[explosive]] and is too sensitive for any practical use unless handled in [[Solution (chemistry)|solution]].


==Preparation==
==Preparation==
Copper azide can be prepared by a [[metathesis reaction]] between [[copper(II) nitrate]] (Cu(NO<sub>3</sub>)<sub>2</sub>) and [[sodium azide]].
Copper azide can be prepared by a [[Salt metathesis reaction|metathesis reaction]] between water-soluble sources of {{chem2|Cu(2+)}} and [[azide]] ions. ([[Spectator ions]] omitted in reaction below).


:{{chem2|Cu(2+) + 2 N3− → Cu(N3)2}}
:Cu(NO<sub>3</sub>)<sub>2</sub> + 2 NaN<sub>3</sub> → Cu(N<sub>3</sub>)<sub>2</sub> + 2 NaNO<sub>3</sub>

It can be destroyed by concentrated nitric acid to form non-explosive products, these being nitrogen, nitrogen oxides and copper(II) nitrate.
