Chemische Eigenschaften
Black powder.
Verwenden
Nickel salts.
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.
Sicherheitsprofil
Confirmed carcinogen
with experimental carcinogenic and
tumorigenic data. Poison by subcutaneous
route. See also NICKEL COMPOUNDS.
m?gliche Exposition
It may be found in the workplace as a
dust, liquid, or acid solution. This compound may be used
in nickel plating operations.
