Fertilisers

Ammonia Fertilisers.

Ammonia fertilisers are produced by the
neutralisation of ammonia with a mineral acid.
Ammonia contains nitrogen and is used to make fertilisers.

The main fertiliser is ammonium nitrate.
This is produced by the reaction of ammonia with nitric acid.

nitric acid    +    ammonia    arrow    ammonium nitrate.
HNO3(aq)    +     NH3(aq)      arrow           NH4NO3(aq)

The above reaction is an example of neutralisation,
making a neutral salt.

The reaction of ammonia with sulfuric acid
would make ammonium sulfate (NH4)2SO4(aq)

Ammonium nitrate has a higher percentage of nitrogen
than ammonium sulfate for the same mass of fertiliser.
