Cline s reagent No. 4 for sulphide concentrations between 250 and 1000 /xmol/L is used. Mixed diamine solution Dissolve 20 g of A,fV-dimethyl-p-phenylenediamine dihydrochloride and 30 g of iron(///) chloride, FeCls, in 500 mL of 6mol/L HCl (cool, a. g.). The reagent is stable for several months. 

The iron with a valence of 2 is referred to as ferrous in compounds (e.g., ferrous chloride = FeCy. When the valence is 3, it is called ferric (e.g., ferric chloride = FeCl ). 

The apparent exceptions to this hypothesis disappear on investigation thus iron, which is a dyad in ferrous compounds (as FeCl,), a tetrad in cubical pyrites (FeS,"), and a hexad in ferric acid (FeO,Ho,), is apparently a triad in ferric chloride (FeCl,) but the vapour-density of ferric chloride shows that its formula must be doubled—that, in ct, the two atoms of the hypothetical molecule of iron (FeJ have not been com-... 

A battery system closely related to Na-S is the Na-metal chloride cell. The cell design is similar to Na-S however, iu addition to the /3-alumina electrolyte, the cell also employs a sodium chloroaluminate, NaAlCL . molten sail electrolyte. Tlie positive electrode active material consists of a transition metal chloride such as iron(II) chloride, FeCL, or nickel chloride, NiCty, in lieu of molten sulfur. This technology is in a younger state of development than the Na-S. 

Chlorostannate and chloroferrate [110] systems have been characterized but these metals are of little use for electrodeposition and hence no concerted studies have been made of their electrochemical properties. The electrochemical windows of the Lewis acidic mixtures of FeCh and SnCh have been characterized with ChCl (both in a 2 1 molar ratio) and it was found that the potential windows were similar to those predicted from the standard aqueous reduction potentials [110]. The ferric chloride system was studied by Katayama et al. for battery application [111], The redox reaction between divalent and trivalent iron species in binary and ternary molten salt systems consisting of 1-ethyl-3-methylimidazolium chloride ([EMIMJC1) with iron chlorides, FeCb and FeCl j, was investigated as possible half-cell reactions for novel rechargeable redox batteries. A reversible one-electron redox reaction was observed on a platinum electrode at 130 °C. 

Chlorination of ferroalloys (ferroniobium-tantalum) is a more economical and simple alternative [30]. The process is performed on a sodium chloride melt that contains iron trichloride, FeCL. Chlorine is passed through the melt yielding NaFeCfi, which interacts as a chlorination agent with the Fe-Nb-Ta alloy. Chlorination of ferroalloys allows for the production of pure tantalum and niobium pentachlorides, which are used further in the production of high purity oxides and other products. 

Many metals react with halogens to give metal halides. For example, iron gives iron (III) chloride, FeCls, on reaction with chlorine gas. 

How much pure water (H O molar mass 18.01 g) would 81.1 g of iron (ni) chloride (FeCl, molar mass 162.2) be dissolved iu to make a solution with a molality of 1.5 m7... 

Varma and his coworkers have described a simple and eflRcient procedure wherein aromatic nitro compounds are readily reduced to the corresponding amino compounds in good yields with hydrazine hydrate supported on alumina in the presence of iron(III) chloride (FeCls 6H2O), Fe(III) hydroxide, or Fe(III) oxides (Scheme 8.60) [159]. 

Identification Signal (Formula 130) the yellow (Formula 131) with iron powder seems to be more practical than the above-mentioned. Experimental mixtures of iron powder, HC, and potassium chlorate, developed by the Chemical Corps in World War react vigorously with water and may ignite spontaneously if moistened. The color effect is due to dispersion of ferric chloride (FeCl,). 

In the Stock system, FeCl2 would be called iron(II) chloride, FeCls would be iron(III) chloride, and PbBr4 would be called lead(IV) bromide. The lUPAC naming system uses the Stock method.
