What is Ferrous ammonium sulfate hexahydrate?
Chemical properties
Ferrous ammonium sulfate hexahydrate is pale blue-green solid
Chemical properties
Ferrous ammonium sulfate is a pale green or blue-green solid (powder or lumpy crystals).
The Uses of Ferrous ammonium sulfate hexahydrate
Used as analytical standard.
The Uses of Ferrous ammonium sulfate hexahydrate
Ammonium iron(II) sulfate hydrate is widely utilized in analytical chemistry for titration purposes since it is affected lesser by oxygen in the air than iron(II) sulpahte. It is employed to measure high doses of gamma rays by using Fricke's dosemeter. It is involved in a variety of other applications from nanomaterials to general redox reactions. It is used in the medical field as an antianemic agent for treatment of iron deficiency.
What are the applications of Application
Ammonium iron(II) sulfate hexahydrate is an analytical standard which is more resistant to oxidation than iron(II) sulfate
Definition
ChEBI: A hydrate that is the hexahydrate form of ferrous ammonium sulfate. Acts as an iron ion donor for building Fe-S clusters in vitro.
Potential Exposure
Ferrous ammonium sulfate hexahydrate is used in photography, analytical chemistry and in dosimeters.
Purification Methods
A solution in warm water (0.67g/mL) is cooled rapidly to 0o, and the resulting light bluish-green monoclinic crystals are filtered at the pump, washed with cold distilled water and pressed between sheets of filter paper to dry it. The solubility at 25o is 0.36g/mL. It separates as an almost white powder when a saturated aqueous solution is diluted with EtOH.
