Neither Raney nickel itself nor any filter residues should be allowed to dry out, otherwise they will spontaneously ignite in air. Stir Raney nickel (also: Urushibara nickel) in the form of an aqueous suspension into hydrochloric acid (Cat. P308 + P313: IF exposed or concerned: Get medical advice/ attention.Ħ.1D Non-combustible, acute toxic Cat.3 / toxic hazardous materials or hazardous materials causing chronic effectsġ5 Heavy metal-containing solutions and solids: container E. Remove contact lenses, if present and easy to do. P305 + P351 + P338: IF IN EYES: Rinse cautiously with water for several minutes. P302 + P352: IF ON SKIN: Wash with plenty of water. P301 + P312: IF SWALLOWED: Call a POISON CENTER/doctor if you feel unwell. P280: Wear protective gloves/ protective clothing/ eye protection/ face protection/ hearing protection. H410: Very toxic to aquatic life with long lasting effects. H341: Suspected of causing genetic defects. H334: May cause allergy or asthma symptoms or breathing difficulties if inhaled. H317: May cause an allergic skin reaction. Cobalt(II) carbonate powder may irritate the skin, eye, and/or respiratory tract.H302: Harmful if swallowed.It is also used in animal feeds as cobalt carbonate aids in the production of vitamin B12 in ruminants such as cattle and sheep.As cobalt is an essential element, it is a component of dietary supplements.It is used as a temperature indicator and veterinary medication.It is used in porcelain colouring, pigments, fertilizers, and catalysts.Cobalt(II) carbonate is used in the preparation of various cobalt compounds.When cobalt (II) carbonate is heated, it emits carbon dioxide and produces cobalt (IV) oxide, which converts reversibly to cobalt oxide (CoO) at high temperatures.ĦCoCO 3 + O 2 → 2 Co 3O 4 + 6CO 2 Uses of Cobalt(II) carbonate.When cobalt (II) carbonate and acetylacetone (C 5H 8O 2) react in the presence of hydrogen peroxide, tris(acetylacetonate)cobalt(III) is produced.ĢCoCO 3 + H 2O 2 + 15C 5H 8O 2 → 2 Co(C 5H 7O 2) 3 + 2CO 2 + 4H 2O.Cobalt chloride hexahydrate can be prepared from the reaction of cobalt II carbonate and hydrochloric acid in an aqueous solution.ĬoCO 3 + 2HCl + 5H 2O → Cl 2 + CO 2.Cobalt (II) carbonate and hydrochloric acid react in an aqueous solution to form Cobalt chloride.ĬoCO 3 + 2HCl(aq) → CoCl 2(aq) + CO 2 + H 2O.Cobalt III Carbonate (Co 2(CO 3) 3) is formed when cobalt II carbonate is oxidized by air on weak oxidizing agents.Soluble in acids and liquid ammonia, almost insoluble in water, alcohol, methyl acetate, and Insoluble in ethanolĬhemical Properties of Cobalt II Carbonate Physical Properties of Cobalt II Carbonate Chemical formula The crystal structure of cobalt II carbonate (anhydrous) is rhombohedral, and cobalt II carbonate hexahydrate is trigonal. The molecular formula of cobalt II carbonate is CoCO 3, and its canonical SMILES is C(=O)(). It is used in the preparation of cobalt compounds, ceramics, pigments, fertilizers, and catalysts. It is soluble in acids and liquid ammonia, almost insoluble in alcohol, methyl acetate, water, and decomposes in hot water, and is insoluble in ethanol. Cobalt (II) carbonate hexahydrate on heating becomes anhydrous by 140 ☌ while the anhydrous cobalt (II) carbonate decomposes at 427 ☌ before melting into cobalt (II) oxide. Spherocobaltite or sphaerocobaltite is a cobalt carbonate mineral that exists in a rose-red colour in its rare pure form, while its impure specimens exist in shades of pink to pale brown. It is an intermediate in obtaining cobalt from their ores by hydrometallurgical purification. Its molecular weight is 118.941 g/mol and it has a density of 4.13 g/cm 3. It is a reddish paramagnetic solid whose chemical or molecular formula is CoCO 3.
