Producing Ammonium Sulfate

Producing ammonium sulfate

Ammonium sulfate (\((\text{NH}_{4})_{2}\text{SO}_{4}\)) can be produced industrially through a number of processes, one of which is the reaction of ammonia with sulfuric acid to produce a solution of ammonium sulfate according to the acid-base reaction below:

\(2\text{NH}_{3}(\text{g}) + \text{H}_{2}\text{SO}_{4}(\text{l})\) \(\rightleftharpoons\) \((\text{NH}_{4})_{2}\text{SO}_{4}(\text{s})\)

The ammonium sulfate solution is concentrated by evaporating the water until ammonium sulfate crystals are formed.
