2. Ammonium iron(III) sulfate - Wikipedia

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

   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.

3. Ammonium iron(II) sulfate - Wikipedia

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

   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 ...

4. Lysine iron agar - Wikipedia

   en.wikipedia.org/wiki/Lysine_iron_agar

   A liter of lysine iron agar contains 13.5g of the gelling agent agar, as well as the nutrients lysine (10 g), pancreatic digest of gelatin (5 g), yeast extract (3 g), glucose (1 g), ferric ammonium citrate (0.5 g), and sodium thiosulfate pentahydrate (40 mg). Additionally, 20 mg of the indicator bromcresol purple is added.

5. 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 ...

6. 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".

7. Ferrous - Wikipedia

   en.wikipedia.org/wiki/Ferrous

   The adjective ferric is used instead for iron(III) salts, containing the cation Fe 3+. The word ferrous is derived from the Latin word ferrum, meaning "iron". In ionic compounds (salts), such an atom may occur as a separate cation (positive ion) abbreviated as Fe 2+, although more precise descriptions include other ligands such as water and ...

8. Jarosite - Wikipedia

   en.wikipedia.org/wiki/Jarosite

   Jarosite is a basic hydrous sulfate of potassium and ferric iron (Fe-III) with a chemical formula of KFe 3 (SO 4) 2 (OH) 6.This sulfate mineral is formed in ore deposits by the oxidation of iron sulfides.

9. 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).
