Ferrous tungstate (FeWO 4) is an inorganic compound. It can be synthesized from iron(III) chloride and sodium tungstate under hydrothermal conditions with the presence of L- cysteine reduces Fe 3+ to Fe 2+ . [ 1 ]
Iron(II) perchlorate is the inorganic compound with the formula Fe(ClO 4) 2 ·6H 2 O.A green, water-soluble solid, it is produced by the reaction of iron metal with dilute perchloric acid followed by evaporation of the solution: [3]

Founded in 1889 and headquartered in The Woodlands, Texas , CB&I designs, fabricates and installs storage tanks and terminals, along with a range ...
Casting pig iron at the Iroquois smelter in Chicago between 1890 and 1901 The Chinese were already making pig iron during the later Zhou dynasty (which ended in 256 BC). [ 5 ] Furnaces such as Lapphyttan in Sweden may date back as far back as the 12th century; and some in the County of Mark dating back to the 13th century, which is now part of ...
The adjective ferrous or the prefix ferro-is often used to specify such compounds, as in ferrous chloride for iron(II) chloride (FeCl 2). 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".
Although anhydrous ferrous acetate can be viewed as a simple salt, X-ray crystallography reveals a complicated polymeric structure. [1] Color code: red = O, blue = Fe, gray = C, white = H. Iron powder reacts with acetic acid to give the ferrous acetate, with evolution of hydrogen gas: [5] [1] Fe + 2 CH 3 CO 2 H → Fe(CH 3 CO 2) 2 + H 2
Ferrous citrates are produced by treating disodium citrate Na 2 C 6 H 6 O 7 with sources of iron(II) aquo complexes, such as iron(II) sulfate. [5] [2] Ferrous citrates are all highly unstable in air, converting to ferric citrates. It is a nutrient supplement approved by the FDA. [6] [7]
Iron(II) oxide or ferrous oxide is the inorganic compound with the formula FeO. Its mineral form is known as wüstite . [ 3 ] [ 4 ] One of several iron oxides , it is a black-colored powder that is sometimes confused with rust , the latter of which consists of hydrated iron(III) oxide (ferric oxide).
