Anwendungen & Verwendung
Beschreibung
Das Dodecahydrat des Ammoniumeisen(III)-sulfat bildet in reinem Zustand farblose Oktaeder, die meist durch Spuren von Mangan blassviolett gefärbt sind. Neben der oben beschriebenen Methode kann es auch durch Zusammengeben stöchiometrischen Mengen Eisen(III)-sulfat und Ammoniumsulfat in Lösung mit anschließendem Abkühlen dargestellt werden. Verwendung fand das Salz in der Textil-Industrie als Beizmittel beim Färben und Drucken.
Herstellung & Synthese
synthetische
Ferric ammonium sulfate is prepared by mixing an equimolar solution offerric sulfate, Fe2(SO4)3, and ammonium sulfate, (NH4)2SO4. Hydrated crystals are obtained following evaporation and cooling of the solution.
