Cobalt(II) oxide (1307-96-6)
Cobalt(II) oxide or cobalt monoxide is an inorganic compound that appears as olive-green to red crystals, or as a greyish or black powder. It is used extensively in the ceramics industry as an additive to create blue colored glazes and enamels as well as in the chemical industry for producing cobalt(II) salts.
Cobalt nitrate (10026-22-9, 10141-05-6, 10141-05-6, 14216-74-1)
cobaltous nitrate · cobaltous nitrate dodecahydrate · cobaltous nitrate trihydrate
Cobalt Nitrate is the inorganic cobalt(II) salt of nitric acid, often with various amounts of water. It is more commonly found as a hexahydrate, Co(NO3)2·6H2O, which is a red-brown deliquescent salt that is soluble in water and other polar solvents.
Cobalt(II) acetate (71-48-7, 6147-53-1, 71-48-7, 5931-89-5)
Cobalt(II) acetate is the cobalt(II) salt of acetic acid. It is commonly found as the tetrahydrate Co(C2H3O2)2·4 H2O or Co(CH3COO)2·4 H2O also abbreviated Co(OAc)2·4 H2O. It is used as an industrial catalyst.
Cobalt(II) fluoride (10026-17-2)
Cobalt(II) fluoride is a chemical compound with the formula (CoF2). It is a pink crystalline solid compound which is antiferromagnetic at low temperatures (TN=37.7 K) The formula is given for both the red tetragonal crystal, (CoF2), and the tetrahydrate red orthogonal crystal, (CoF2·4H2O). CoF2 is used in oxygen-sensitive fields, namely metal production.
Cobalt bromide (7789-43-7, 12789-07-0)
cobalt dibromide · tetraaquacobalt(II) bromide dihydrate · cobalt bromide hexahydrate
Cobalt(II) bromide (CoBr2) is an inorganic compound. It is a red solid that is soluble in water, used primarily as a catalyst in some processes.
Cobalt(II) chloride (7646-79-9)
cobalt chloride · cobaltous chloride · cobalt dichloride
Cobalt(II) chloride is an inorganic compound of cobalt and chlorine, with the formula CoCl2. It is usually supplied as the hexahydrate CoCl2·6H2O, which is one of the most commonly used cobalt compounds in the lab. The hexahydrate is purple, whereas the anhydrous form is sky blue.
Cobalt(III) oxide (1308-04-9)
Cobalt (III) oxide is the inorganic compound with the formula of Co2O3, most commonly used in bleach. Although only two oxides of cobalt are well characterized, CoO and Co3O4, procedures claiming to give Co2O3 have been described. Thus treatment of Co(II) salts such as cobalt(II) nitrate with an aqueous solution of sodium hypochlorite (also known as bleach) gives a black solid.
Cobaltous phosphate (13455-36-2)
Cobalt phosphate is the inorganic compound with the formula Co3(PO4)2. It is a commercial inorganic pigment known as cobalt violet. Thin films of this material catalyze the decomposition of water.
Chloropentamminecobalt chloride is the dichloride salt of the coordination complex [Co(NH3)5Cl]2+. It is a red-violet, diamagnetic, water-soluble salt. The compound has been of academic and historical interest.
Cobalt fluoride (CoF3) (10026-18-3)
Cobalt(III) fluoride is the inorganic compound with the formula CoF3. This highly reactive, hygroscopic brown solid is used to synthesize organofluorine compounds. CoF3 is a powerful fluorinating agent that leaves CoF2 as the byproduct.
