Nickel(II) nitrate hexahydrate Chemical Properties,Usage,Production

  • Description Nickel (II) nitrate hexahydrate is the hexahydrate form of the nickel (II) nitrate. Nickel nitrate (chemical formula: Ni(NO3)2) is manufactured by the reaction of nickel oxide with nitric acid. The nickel (II) nitrate hexahydrate can be used as a precursor during the manufacturing of other nickel salts and supported nickel catalysts. For example, it is the precursor for the manufacturing of nickel sulfide-reduced graphene oxide (RGO) composite powders. It can also be used for the manufacturing of nickel and nickel oxide nanocrystals impregnated O-MWCNTs which is useful in semiconductor industries. Moreover, it can also be used in electroplating and as a mordent in textile dyeing. Finally, it can be used to improve the cycling stability and rate capability o Li2MnO2.
  • Preparation Nickel nitrate hexahydrate may be prepared by several methods based on the reaction of dilute nitric acid on nickel powder, nickel oxide or nickel carbonate. The reaction is exothermic and requires controlled cooling during production. The hexahydrate can be dehydrated to anhydrous salt by treatment with fuming nitric acid.

  • Description Nickel (II) nitrate hexahydrate appears as green crystals and substantially soluble in water. It is stable, a strong oxidiser, and incompatible with reducing agents. It has wide industrial applications in nickel plating as catalysts and is indirectly associated with other industries of nickel alloy manufacturers, nickel miners, smelters and refiners, nickel platers, and exposure to alloys, for example, in coinage.
  • Chemical Properties Green crystal
  • Preparation Emerald green crystals of the hexahydrate Ni(N03)2?6H20 crystallize from aqueous solutions at room temperature. These are isomorphous with the corresponding cobalt(II) salt containing the regular octahedral [Ni(H20)6]2+ ions with Ni-O distances = 2.03 A. The tetrahydrate crystallize above 54° and the dihydrate above 85.4°. The pale green anhydrous nitrate can be obtained by dehydration of the hydrate with dinitrogen pentoxide in fuming nitric acid or by the liquid phase reaction of dinitrogen tetroxide with nickel carbonyl [the gas phase reaction gives the nitrite Ni(N02)2]
    Ni(CO)4+2N2O4 -* Ni(N03)2+2NO+4CO
    The first product of this latter rather violent reaction is the adduct Ni(NO3)2N2O4 from which the nitrogen tetroxide is removed by heating in vacuo. It can also be prepared by the reaction of dinitrogen tetroxide-ethyl acetate mixtures with nickel(II) chloride. The infrared spectrum shows it to be a typical covalent nitrate. It is involatile and decomposes upon heating in nitrogen to give the nitrite Ni(NO2)2 above 260°.
  • Safety Profile Confirmed carcinogen. Moderately toxic by ingestion. When heated to decomposition it emits toxic fumes of NOx. See also NICKEL(II) NITRATE.
  • Purification Methods Crystallise it from water (3.3g/mL) by partial evaporation in a desiccator. Store it in a desiccator as it is deliquescent.
