2. Iron (II) sulfate - Wikipedia

   en.wikipedia.org/wiki/Iron(II)_sulfate

   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 ...

3. Iron(III) sulfate - Wikipedia

   en.wikipedia.org/wiki/Iron(III)_sulfate

   Iron(III) sulfate (or ferric sulfate), is a family of inorganic compounds with the formula Fe 2 (SO 4) 3 (H 2 O) n. A variety of hydrates are known, including the most commonly encountered form of "ferric sulfate". Solutions are used in dyeing as a mordant, and as a coagulant for industrial wastes. Solutions of ferric sulfate are also used in ...

4. Fenton's reagent - Wikipedia

   en.wikipedia.org/wiki/Fenton's_reagent

   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

6. Copperas works - Wikipedia

   en.wikipedia.org/wiki/Copperas_works

   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

7. Iron - Wikipedia

   en.wikipedia.org/wiki/Iron

   Iron(II) sulfate is used as a precursor to other iron compounds. It is also used to reduce chromate in cement. It is used to fortify foods and treat iron deficiency anemia. Iron(III) sulfate is used in settling minute sewage particles in tank water.

8. Vitriol - Wikipedia

   en.wikipedia.org/wiki/Vitriol

   A Many websites state that black vitriol "is a mixture of iron sulfate and iron sulfite", but none give a reference of any sort. The book, Chemistry, Inorganic & Organic, with Experiments, by Bloxam [4] is a published, reliable reference for the composition of black vitriol, and it states on page 513, "The formula of black vitriol may be written [CuMgFeMnCoNi]SO 4 ·7H 2 O, the six isomorphous ...

9. Iron gall ink - Wikipedia

   en.wikipedia.org/wiki/Iron_gall_ink

   Homemade iron gall ink in use, displaying the delayed darkening of the ink Ink corrosion: iron gall ink causes paper and parchment to disintegrate. By mixing tannin with iron sulfate, a water-soluble ferrous tannate complex is formed. Because of its solubility, the ink is able to penetrate the paper surface, making it difficult to erase.
