What is the Ammonium Sulphate? How to prepared it ...

The sulphate is obtained from gypsum sulphate acid. Ammonia is rected with either gypsum or sulphuric acid to yield ammonium sulphate. In the destructive distillation of coal, some volatile substances such as finely divided tar, ammonia, and other gases are formed. Ammonium may be recovered by cooling and bubbling it through the water.
