Full Answer

Ammonium iron(II) sulfate is obtained from iron, ammonia and sulfuric acid, while the hexahydrate is produced by a reaction between ammonium sulfate and ferrous sulfate. Commonly, a very pure form of Mohr's salt is used during the process of titration. It is also used in Fricke's dosemeter in order to measure large doses of gamma rays.
