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 ...
Mohr's salt, ammonium iron(II) sulfate, [NH 4] 2 [Fe(H 2 O) 6](SO 4) 2.. A double salt is a salt that contains two or more different cations or anions.Examples of double salts include alums (with the general formula M I M III (SO 4) 2 ·12H 2 O) and Tutton's salts (with the general formula (M I) 2 M II (SO 4) 2 ·6H 2 O).

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.
Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula Fe SO 4 ·xH 2 O. These compounds exist most commonly as the heptahydrate (x = 7) but several values for x are known. The hydrated form is used medically to treat or prevent iron deficiency, and also for industrial applications.
Typically iron(II) salts, like the "chloride" are aquo complexes with the formulas [Fe(H 2 O) 6] 2+, as found in ferrous ammonium sulfate. [5] The aquo ligands on iron(II) complexes are labile. It reacts with 1,10-phenanthroline to give the blue iron(II) derivative: When metallic iron (oxidation state 0) is placed in a solution of hydrochloric ...
Calcium carbonate precipitates as a solid, leaving ammonium sulfate in the solution. (NH 4) 2 CO 3 + CaSO 4 → (NH 4) 2 SO 4 + CaCO 3. Ammonium sulfate occurs naturally as the rare mineral mascagnite in volcanic fumaroles and due to coal fires on some dumps. [14] Ammonium sulfate is a byproduct in the production of methyl methacrylate. [15]
Fenton's reagent is a solution of hydrogen peroxide (H 2 O 2) and an iron catalyst (typically iron(II) sulfate, FeSO 4). [1] It is used to oxidize contaminants or waste water as part of an advanced oxidation process. Fenton's reagent can be used to destroy organic compounds such as trichloroethylene and tetrachloroethylene (perchloroethylene).
The formation of Fe(III)-EDTA (FeY) − can be described as follows: FeSO 4 ∙7H 2 O + K 2 H 2 Y + 1/4 O 2 → K[FeY(H 2 O)]. H 2 O + KHSO 4 + 5.5 H 2 O (1) [8]. Iron chelate has also been used as a bait in the chemical control of slugs, snails and slaters in agriculture in Australia and New Zealand.
