Ferrous ammonium sulfate hexahydrate is pale blue-green solid??
Used as analytical standard.??
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.??? ??
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.???(II) ??? ????? ?? ?? ? ???
