Upon inhalation of salts, there is some evidence for carcinogenicity. Rarely have poisonings resulted from cobalt compounds. Health issuesĬobalt is essential for most higher forms of life, but more than a few milligrams each day is harmful. For these purposes, the cobalt sulfate is produced by treating cobalt oxide with sulfuric acid. Cobalt(II) sulfate is used in storage batteries and electroplating baths, sympathetic inks, and as an additive to soils and animal feeds. Cobalt pigment is used in porcelains and glass. Hydrated cobalt(II) sulfate is used in the preparation of pigments, as well as in the manufacture of other cobalt salts. UsesĬobalt is obtained from ores via the sulfate in many cases. Cobalt sulfate Cobaltous sulfate Cobalt(2+) sulfate Cobalt(II) sulfate Cobalt sulphate 1 Cobalt Brown Cobalt monosulfate Cobalt (2+).

It is stable in the dry state, but is decomposed by water with evolution of oxygen it is fairly stable in solution in dilute sulphuric acid. The Index number is the identification code given to substances in Part 3 of Annex VI to the CLP Regulation ((EC) No 1272/2008). The hexahydrate is a metal aquo complex consisting of octahedral 2+ ions associated with sulfate anions. The blue, crystalline hydrate Co2(SO4)3.18H2O is prepared by the oxidation of cobalt(II) sulphate in 8N sulphuric acid either electrolytically or chemically with ozone or fluorine. Following the risk evaluation, Environment Canada recommends that this substance be. 1) was selected for risk evaluation because it is a substance (under the Government of Canada’s Chemicals Management Plan) that, if spilled, could be immediately harmful to humans and/or the environment. It forms by the reaction of metallic cobalt, its oxide, hydroxide, or carbonate with aqueous sulfuric acid.

Sulphuric acid, cobalt (2+) salt (1:1) (CAS No. It is soluble in water, slightly soluble in ethanol, and especially soluble in methanol.

1 Properties, preparation, and structureĬobalt(II) sulfate heptahydrate appears as red monoclinic crystals that liquify around 100 ☌ and become anhydrous at 250 ☌.

On World Health Organization (WHO), the International Agency for Research on Cancer published a preliminary list of carcinogens reference, Cobalt sulfate and other soluble cobalt (II) salts in the 2B list of carcinogens. Animal experiments have confirmed that cobalt sulfate can cause adrenal tumors and lung tumors. Further applications comprise surface treatments (such as electroplating), corrosion prevention, decolorization (in glass, pottery) REACH Candidate List: 0.1 D of 303 Classified as.

H2O (100☌) īrown-yellow red crystals, soluble in water and methanol, ethanol-soluble, easy weathering in the air.Ĭobalt sulfate is widely used as a desiccant for electroplating, ceramic colorants, inks and paints. 1 Cobalt(II) sulphate Cobalt(II) sulphate is mainly used in the manufacture of other chemicals including pigments and possibly catalysts, driers.
