NiCl2 Nickel chloride

Africa)io is a variant of sodium-sulfur technology where sulfur is replaced with a metal chloride such as NiCl2 (nickel chloride) or FeCU. It was specifically developed for applications in electric vehicles, freight transport and public transport the ZEBRA battery is more particularly intended to serve buses and utility vehicles. As with the Na-S battery, the vibrations felt in a vehicle may cause premature aging of the ceramic/metal interface. Today, such batteries are also being considered for stationary applications.

The pathway of delivery seems to be an important determinant in the geno-toxicity of nickel compounds in vitro. Regarding X-chromosome fragmentation in CHO cells [306, 444], nickel chloride was reported to be ineffective by contrast to crystalline NiS. Delivery and uptake by phagocytosis of NiCl2, artificially encapsulated in liposomes, induced fragmentation. 

How would you prepare 250.0 mL of a 50.0 ppm solution of nickel from pure solid nickel chloride hexahydrate, NiCl2- 6 H20, FW = 237.71 g/mol ... 

Nickel chloride forms double salts with alkali metal chlorides or ammonium chloride. Such double salts, NH4Cl NiCl2 6H20, are obtained as hexahydrate when crystallized from a mixed solution of nickel chloride and ammonium chloride in equimolar amounts.. 

Elemental composition (for anhydrous NiCb) Ni 45.30%, Cl 54.70% Percent composition of NiCl2 6H20 Ni 24.69%, Cl 29.83%, H2O 45.48%. Nickel may be analyzed in an aqueous solution of salt by various instrumental techniques (See Nickel). Chloride ion in the aqueous solution may be determined by titration with silver nitrate using potassium chromate indicator or preferably by ion-chromatography. The solutions must be appropriately diluted for all analyses. 

Currently interest has now been directed toward a similar high temperature system, the ZEBRA Battery, which also uses P-alumina as a Na ion conductor. The sulfur electrode is replaced by nickel chloride or by a mixture of ferrous and nickel chlorides. Contact between the NiCl2 electrode and the solid electrolyte is poor as they are both solids, and current flow is improved by adding a second liquid electrolyte (molten NaAlCb) between this electrode and the P-alumina. The overall cell reaction is now ... 

Treatment of a benzene solution of VI with an excess of nickel chloride in methanol resulted in the precipitation of a yellow powder. This was recrystallized from methanol to give air-stable yellow-orange crystals (60%) with the stoichiometry (VI) NiCl2 -3MeOH (by combustion analysis). When this recrystallized complex was treated with excess aqueous sodium cyanide in the presence of CgDg at room temperature for 10 min VI was regenerated, but now the 3 3P NMR absorptions at 6 -58.1 and -64.0 ppm were in an area ratio of 95 5. Similar treatment of VII with nickel chloride led to a dark oily precipitate which required considerable manipulation to partially purify it. Treatment with sodium cyanide as above led to the regeneration of VII also enriched in the major isomer (85 15). 

Thus if an aqueous solution is subjected to electrolysis, one or both of the above reactions may be able to compete with the electrolysis of the solute. This does not happen for the solution of NiCl2 illustrated above, but if we substitute sodium chloride for nickel chloride, hydrogen is produced at the cathode instead of sodium ... 

Nickel salts readily combine with ammonia to fonn ammoniates, as, for example, the hexammoniates of nickel chloride, NiCl2.6NH3, and sulphate, NiS04.6NH3. Palladium salts act similarly.

Doable Chlorides.—Nickel chlorides unite with the chlorides of many other metals, particularly the alkali metals and ammonium, to form double salts. Chief amongst these are nickel ammonium chloride, NH4C1. NiCIa. 6H20, which occurs as green, monoclinic crystals. Nickel lithium ckloride,10 LiCl. NiCl2.6H20, yields deliquescent, golden prisms. 

Monoccesium and diccesium nickel chlorides, CsCl.NiCl2 and 2CsCl.NiCl , respectively, have been prepared,1 and a yellow dirubidium nickel chloride,2 2B.bCl.NiOj. Other double chlorides are known, but their importance is small.3...

In order to determine the apparatus constant iioffAll that appears in Eq. (13), measurements are made on a material of known susceptibihty. Eor this purpose, a common standard is an aqueous solution of nickel chloride, about 30 percent NiCl2 by weight. Prepare 100 mL of such a solution with an accurately known weight fraction of NiCl2 in air-free distilled water. When this and other solutions are weighed on the Gouy balance, record the ambient temperature.
