what happens when ammonium nitrate reacts with water?
endothermic
consumption of can was 3.54 million tonnes in 1973/74, 4.45 million tonnes in 1983/84, 3.58 million tonnes in 1993/94. production of calcium ammonium nitrate consumed 3% of world ammonia production in 2003.









































section::::physical and chemical properties.









































calcium ammonium nitrate is hygroscopic. its dissolution in water is endothermic, leading to its use in some instant cold packs.









































section::::use.
calcium ammonium nitrate
the ammonia required for this process is obtained by the haber process from nitrogen and hydrogen. ammonia produced by the haber process is oxidized to nitric acid by the ostwald process. another production method is a variant of the odda process:









































the products, calcium carbonate and ammonium nitrate, may be separately purified or sold combined as calcium ammonium nitrate.









































ammonium nitrate can also be made via metathesis reactions:









































section::::production.:reactions.









































ammonium nitrate reacts with metal hydroxides, releasing ammonia and forming alkali metal nitrate:









































ammonium nitrate leaves no residue when heated:









































when rapidly heated or exploded the predominant reaction is:
ammonium nitrate
