Ammonium sulfate is a precursor to other ammonium salts, especially ammonium persulfate. Ammonium sulfate is listed as an ingredient for many United States vaccines per the Centers for Disease Control. [12] Ammonium sulfate has also been used in flame retardant compositions acting much like diammonium phosphate.
Ammonium iron(II) sulfate, or Mohr's salt, is the inorganic compound with the formula (NH 4) 2 SO 4 ·Fe(SO 4)·6H 2 O. Containing two different cations, Fe 2+ and NH + 4, it is classified as a double salt of ferrous sulfate and ammonium sulfate. It is a common laboratory reagent because it is readily crystallized, and crystals resist oxidation ...
Ammonium iron(III) sulfate, NH 4 Fe(SO 4) 2 ·12 H 2 O, or NH 4 [Fe(H 2 O) 6](SO 4) 2 ·6 H 2 O, also known as ferric ammonium sulfate (FAS) or iron alum, is a double salt in the class of alums, which consists of compounds with the general formula AB(SO 4) 2 · 12 H 2 O. [2] It has the appearance of weakly violet, octahedrical crystals.
Mascagnite is a rare ammonium sulfate mineral (N H 4) 2 S O 4. It crystallizes in the orthorhombic system typically forming as stalactitic masses exhibiting good cleavage. It is soft (not higher than 2.5 on the Mohs scale) and water-soluble. Optical properties are variable; the purest form is transparent and colorless, but opaque gray or yellow ...
Potassium Nickel Sulfate Hexahydrate [14] used as UV filter [48] Rb Ni Rb 2 [Ni(H 2 O) 6](SO 4) 2: Rubidium Nickel Sulfate Hexahydrate 6.221 12.41 9.131 106.055° 677.43 001 surface has step growth of 4.6 Å, optical transmission bands at 250, 500 and 860 nm which are the same as nickel sulfate hexahydrate, but UV band transmits more.
Letovicite (/ l ɛ t oʊ ˈ v ɪ s aɪ t /) is an ammonium sulfate mineral with composition (NH 4) 3 H(SO 4) 2 (IUPAC: triammonium sulfate hydrogensulfate, Nickel–Strunz classification 07.AD.20). It is a rare colorless or white monoclinic secondary mineral formed during the burning of waste coal heaps and as a deposit in hot springs.
