Multiple intratracheal instillations resulted in malignant lung tumours (adenocarcinomas, squamous-cell carcinomas and mixed tumours).Nickel and nickel compounds are absorbed from the respiratory tract, and to a smaller extent from the gastrointestinal tract, depending on dissolution and cellular uptake. Hydrated nickel (II) is the primary ion in aqueous solutions. It is a good conductor of electricity and heat. Lung effects, including chronic bronchitis, reduced lung function, and lung cancer, as well as nasal effects, including rhinitis, nasal sinusitis, nasal mucosal injury and sinus cancer, have been observed in workers who breathed high levels of nickel while working in nickel refineries or nickel processing plants. NiCl2 ( NICKEL CHLORIDE ) is Soluble in water I'll tell you the Soluble or Insoluble bond list below. The carbonylation residue is further processed to recover precious metals and some nickel and cobalt salts. Its melting point is 230°C and its vapour density is 3.2.Vehicles running on petrol and diesel fuel can contribute to nickel emissions to the atmosphere.Nickel carbonate occurs as light green rhombic crystals or as a brown powder. Table 1. Sources of nickel in water and soil include wastewater from municipal sewage treatment plants. More properties for selected nickel compounds follow.Nickel can be transported as particles released into the atmosphere or as dissolved compounds in natural waters.Synonyms: Raney alloy, Raney nickel, C.I. It is used in the preparation of coloured glass, in the manufacture of certain nickel pigments, as a neutralising compound in nickel electroplating solution, and in the preparation of many specialty nickel compounds.Nickel acetate is used mainly as a mordant in the textile industry, and as a hydrogenation catalyst. Water solubility of nickel compounds vary. It decomposes into nickel oxide and water when heated at elevated temperatures.Coins, jewellery, nickel-cadmium batteries, some paints and ceramics, magnetic tapes, computer components, goods containing stainless steel (sinks, cooking utensils, cutlery).Nickel and compounds can be inhaled or ingested.Nickel is a silvery-white, hard, malleable, ductile, ferromagnetic metal. Other sources of atmospheric nickel include emissions from mining and refining operations, steel production, nickel alloy production, electroplating, and municipal waste incineration. (1) Question: Is NiCl2 ( NICKEL CHLORIDE ) Soluble or Insoluble in water ? Under normal conditions, nickel is overwhelmingly associated with abundant iron and manganese particles which precipitate and absorb free nickel ions. The hydrogenation of finely powdered newspaper with a nickel hydroxide catalyst produces conversion in high yields of cellulose feed materials to liquid hydrocarbon fuels.Exposure to nickel salts can cause 'nickel itch', which causes burning and itching sensations in the hands, followed by abnormal redness of the skin and nodular eruption on the web of fingers, wrists and forearms. Nickel subsulfide has been shown consistently to induce local sarcomas following intramuscular administration, and dose-response relationships were demonstrated in rats and hamsters.
This by-product is further refined to separate and refine nickel and cobalt. It can react violently with iodine, hydrogen sulfide, or a mixture of barium oxide and air.Properties vary widely depending on the particular compound. It dissolves in dilute mineral acids and is insoluble in concentrated nitric acid.Nickel is an abundant element.

Pure nickel is found alloyed with iron in many meteors and the earth's core is believed to contain substantial quantities. It is also used as an intermediate in the formation of other nickel compounds, as a sealer for anodised aluminium, and in nickel electroplating.Nickel hydroxide occurs as either a fine green powder, green crystals, or an amorphous black powder. Nickel and cobalt are extracted from the process liquor by precipitation with hydrogen sulfide, and the mixed nickel-cobalt (10:1) sulfide is further refined in one of the processes described above.The highest risks for lung and nasal cancers were observed among calcining workers, who were heavily exposed to both sulfidic and oxidic nickel.
