Questions And Answer | Back Directory | [Description]
Cobalt Nitrate is the cobalt salt form of nitrate, usually existing in the form of hexahydrate. It is used in manufacture of cobalt pigments and invisible inks; decorating stoneware and porcelain; preparation of catalysts; production of vitamin B12 supplements; a battery additive. It is commonly reduced, acting as the source of metallic high purity cobalt for use in the electronics and related industries. It can be absorbed on to various catalyst supports for use in Fischer-Tropsch catalysis. It also finds application in the synthesis of benzimidazole and benzothiazole compounds, which show significant and promising activities against various viruses such as HIV and HCMV-1.

Red crystal, deliquescent in most air | [Uses]
Cobaltous nitrate [Co(NO3)2·6H2O], also known as cobalt nitrate, is a red crystal that
absorbs moisture. It is used in inks, pigments, animal feed, soil enhancers, and hair dyes. | [Uses]
manufacture of cobalt pigments and invisible inks; decorating stoneware and porcelain; preparation of catalysts; production of vitamin B12 supplements. | [Uses]
Preparation of cobalt standard solutions. | [Definition]
ChEBI: A hydrate that is the hexahydrate form of cobalt dinitrate. | [Preparation]
The red hygroscopic hexahydrate Cu(NO3)2.6H2O crystallizes from aqueous solutions of cobalt bases in dilute nitric acid at room temperature. It becomes the trihydrate when heated at 56° ; at higher temperatures decomposition occurs. | [General Description]
Cobalt(II) nitrate hexahydrate (Co(NO3)2·6H2O) is the hydrated cobalt salt. Its step-wise thermal degradation has been investigated. It affords anhydrous cobalt(II)nitrate as decomposition product. | [Purification Methods]
Crystallise the nitrate from water (1mL/g), or ethanol (1mL/g), by partial evaporation. After 3 crystallisations from H2O it contains: metal (ppm) As (8), Fe (1.2), K (1), Mg (4), Mn (4), Mo (4), Na (0.6), Ni (18), Zn (1.6). The hexahydrate gives the pink anhydrous salt by the action of HNO3 and N2O5. The hexahydrate melts at ~55o to give a red liquid which decomposes on further heating at 100-105o to form Co3O4. |
