How can we prepare ammonium nitrate in a laboratory?
Neutralising nitric acid with ammonia produces a solution of ammonium nitrate. The salt can be crystallised from solution but it is very important not to heat the solution to dryness.
Ammonium nitrate decomposes on heating. Under some circumstances the decomposition is explosive.
