Iron(II) sulfate outside a titanium dioxide factory in Kaanaa, Pori, Finland. Upon dissolving in water, ferrous sulfates form the metal aquo complex [Fe(H 2 O) 6] 2+, which is an almost colorless, paramagnetic ion. On heating, iron(II) sulfate first loses its water of crystallization and the original green crystals are converted into a white ...
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 iron compounds produced on the largest scale in industry are iron(II) sulfate (FeSO 4 ·7H 2 O) and iron(III) chloride (FeCl 3). The former is one of the most readily available sources of iron(II), but is less stable to aerial oxidation than Mohr's salt ((NH 4) 2 Fe(SO 4) 2 ·6H 2 O). Iron(II) compounds tend to be oxidized to iron(III ...
Copperas house, Limb Valley. Copperas (iron(II) sulfate) was manufactured here from the pyritic Ringinglow coal seam, mined nearby. The copperas solution was used in the leather tanning industry. Copperas works are manufactories where copperas (iron(II) sulfate) is produced from pyrite, often obtained as a byproduct during coal mining, and iron
Green rust is a generic name for various green crystalline chemical compounds containing iron(II) and iron(III) cations, the hydroxide (OH −) anion, and another anion such as carbonate (CO 2− 3), chloride (Cl −), or sulfate (SO 2− 4), in a layered double hydroxide (LDH) structure. The most studied varieties are the following: [1]
Iron(II) selenate can be prepared by the reaction of saturated sodium selenate and iron(II) sulfate at 80 °C. When cooled to room temperature, crystalline iron(II) selenate precipitates from the solution. [4] Na 2 SeO 4 (sat.) + FeSO 4 → Na 2 SO 4 + FeSeO 4. The reaction of iron and selenic acid produces iron(II) selenate as well, but with a ...
Tutton's salts are a family of salts with the formula M 2 M'(SO 4) 2 (H 2 O) 6 (sulfates) or M 2 M'(SeO 4) 2 (H 2 O) 6 (selenates). These materials are double salts, which means that they contain two different cations, M + and M' 2+ crystallized in the same regular ionic lattice. [1]
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).
