Iron(II) chloride, also known as ferrous chloride, is the chemical compound of formula FeCl2. Convert grams Iron(II) Chloride to moles or moles Iron(II) Chloride to grams, Molecular weight calculation: This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. Name: Iron (II) Chloride. This reaction gives the methanol solvate of the dichloride, which upon heating in a vacuum at about 160 °C converts to anhydrous FeCl2. Iron dichloride. In one of two classic syntheses of ferrocene, Wilkinson generated FeCl2 in situ by comproportionation of FeCl3 with iron powder in THF. Iron chloride (FeCl2) More... Molecular Weight: 126.75 g/mol. Create . ›› Iron(II) Chloride Tetrahydrate molecular weight. 55.845 + 35.453*2. There is also a dihydrate. Lawrencite, (Fe,Ni)Cl2, is the natural counterpart, and a typically (though rarely occurring) meteoritic mineral. Molecular weight calculation: 55.845 + 35.453*2 ›› Percent composition by element Iron (II) Chloride. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. Convert grams Iron(II) Chloride to moles or moles Iron(II) Chloride to grams. Such solutions are designated "spent acid," or "pickle liquor" especially when the hydrochloric acid is not completely consumed: The spent acid requires treatment if it is disposed. FeCl2 crystallizes from water as the greenish tetrahydrate, which is the form that is most commonly encountered in commerce and the laboratory. Structure of anhydrous ferrous chloride (, Except where otherwise noted, data are given for materials in their, Egon Wildermuth, Hans Stark, Gabriele Friedrich, Franz Ludwig Ebenhöch, Brigitte Kühborth, Jack Silver, Rafael Rituper “Iron Compounds” in, National Institute for Occupational Safety and Health, https://en.wikipedia.org/w/index.php?title=Iron(II)_chloride&oldid=988832034, Chemical articles with multiple compound IDs, Multiple chemicals in an infobox that need indexing, Chemical articles with multiple CAS registry numbers, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Creative Commons Attribution-ShareAlike License, This page was last edited on 15 November 2020, at 14:38. The compound is white, but typical samples are often off-white. Calculate the molecular weight molar mass and molecular weight. Convert grams Iron(II) Chloride Tetrahydrate to moles or moles Iron(II) Chloride Tetrahydrate to grams. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. The reason is that the molar mass of the substance affects the conversion. It is the precursor to hydrated iron(III) oxides that are magnetic pigments. Answer to: Suppose 49.9 g of iron (II) chloride is dissolved in 350.0 mL of 0.600 M aqueous solution of silver nitrate. , Unlike the related ferrous sulfate and ferric chloride, ferrous chloride has few commercial applications. FeCl2 crystallizes from water as the greenish tetrahydrate, which is the form that is most commonly encountered in commerce and the laboratory.  The net reaction is shown: FeBr2 and FeI2 can be prepared analogously.

Iron(II) chloride. It is used as a precursor to make various grades of hematite that can be used in a variety of pigments. Ferrous chloride can also be used to regenerate hydrochloric acid. FeCl2 is used to generate NHC complexes in situ for cross coupling reactions. The compound is highly soluble in water, giving pale green solutions. Aside from use in the laboratory synthesis of iron complexes, ferrous chloride serves as a coagulation and flocculation agent in wastewater treatment, especially for wastes containing chromate or sulfides. Formula of iron(II) chloride hexahydrate = FeCl26H2O Molar mass = Molar mass of FeCl2+ 6(Molar mass of view the full answer Previous question Next question Get more help from Chegg FeCl2. Hydrated forms of ferrous chloride are generated by treatment of wastes from steel production with hydrochloric acid. To complete this calculation, you have to know what substance you are trying to convert.
