Chemische Eigenschaften
Nickel hydroxide is a light, apple-green powder.
Chemische Eigenschaften
Black powder.
Verwenden
Nickel salts.
Verwenden
Nickel hydroxide was used as a reference material in a study where the influence of stacking faults on the electrochemical activity of Ni(OH)₂ electrodes was studied.
Verwenden
Due to its redox behavior, it finds use in rechargeable battery electrodes. It is useful for the storage of electrochemical energy, with potential applications in car batteries. It is a potential material for several biological applications, for example in chromosomal DNA quantification assay.
synthetische
This is precipitated as finely divided green powder when an alkali metal hydroxide solution is added to an aqueous solution of a nickel(II) salt. It is frequently difficult to filter at first but becomes more crystalline upon prolonged standing. If the nickel salt is incompletely precipitated, especially if very strong solutions of nickel(II) are used, then the precipitate may be a basic salt. This is particularly true of the halides, in which case compounds such as NiCl2?3Ni(OH)2 and NiCl2?Ni(OH)2 have been characterized.
Vorbereitung Methode
Nickel hydroxide is obtained either by treating nickel sulfate solution with sodium hydroxide or by hot alcohol extraction of the precipitate formed as a result of the reaction of nickel nitrate with potassium hydroxide. Nickel hydroxide is used for the manufacture of nickel–cadmium electric cells, and as an intermediate product during the manufacture of nickel catalysts.
Hazard
Confirmed carcinogen.
Flammability and Explosibility
Non flammable
Sicherheitsprofil
Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Poison by subcutaneous route. See also NICKEL COMPOUNDS.
mögliche Exposition
It may be found in the workplace as a dust, liquid, or acid solution. This compound may be used in nickel plating operations.
Versand/Shipping
UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard Class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
Inkompatibilitäten
Incompatible with strong acids. Aqueous solution may be acidic.
Waste disposal
Recover and recycle where possible or dispose of in a chemical waste landfill.
