Ammonium nitrite is an ammonium salt of nitrous acid . It has the formula NH 4 NO 2 .
properties
Ammonium nitrite forms colorless, needle-shaped crystals. The connection is unstable and is very easily oxidized by atmospheric oxygen even at room temperature , which can be accelerated even further by high humidity. The crystals turn yellow.
hazards
If the ammonium nitrite is heated in its crystal form, it explodes from a temperature of 60–70 ° C. However, smaller impacts are also sufficient to cause spontaneous explosions.
Reactions
Ammonium nitrite breaks down into nitrogen and water :
use
Ammonium nitrite can be used to synthesize hydroxylamine . It is also suitable as a solid nitrogen source , for example to synthesize salts of NH 2 OH.
