Cobalt(II) sulfate heptahydrate. Cobalt(II) sulfate is any of the inorganic compounds with the formula CoSO 4 (H 2 O) x. Usually cobalt sulfate refers to the hexa- or heptahydrates CoSO 4. 6H 2 O or CoSO 4. 7H 2 O, respectively. [1] The heptahydrate is a red solid that is soluble in water and methanol. Since cobalt(II) has an odd number of ...
Cobalt is an essential element for health in animals in minute amounts as a component of vitamin B 12. A deficiency of cobalt, which is very rare, is also potentially lethal, leading to pernicious anemia. [1] Exposure to cobalt metal dust is most common in the fabrication of tungsten carbide. [2]
Cobalt can easily react with nitric acid to form cobalt(II) nitrate Co(NO 3) 2. Cobalt(II) nitrate exists in the anhydrous form and the hydrate form, of which the hexahydrate is the most common. Cobalt nitrate hexahydrate (Co(NO 3) 2 ·6H 2 O) is a red deliquescence crystal that is easily soluble in water, [12] and its molecule contains cobalt ...
In the United States, the Federal Hazardous Substances Labeling Act of 1960, the Toy Safety Act of 1969, the Consumer Product Safety Commission, established in 1972, and the Toxic Substances Control Act of 1976 all introduced new levels of regulation, [4] which led to the decline of chemistry sets' popularity during the 1970s and 1980s. [13]
Cobalt(II) azide is an inorganic chemical compound with the formula Co(N 3) 2. It can be formed through the reaction between dicobalt octacarbonyl and iodine azide. [1] Co 2 (CO) 8 + 4IN 3 → 2Co(N 3) 2 + 8CO + 2I 2
NFPA 704 safety squares on containers of ethyl alcohol and acetone. "NFPA 704: Standard System for the Identification of the Hazards of Materials for Emergency Response" is a standard maintained by the U.S.-based National Fire Protection Association.
The salt is prepared with a two-step process starting with oxidizing a solution of cobalt chloride and ammonia. [1] [2] 2 CoCl 2 ·6H 2 O + 10 NH 3 + 2 HCl + H 2 O 2 → 2 [Co(NH 3) 5 (OH 2)]Cl 3 + 12 H 2 O. This intermediate is then heated to induce coordination of one of the outer sphere chloride ligands: [Co(NH 3) 5 (OH 2)]Cl 3 → [Co(NH 3 ...
Cobalt(II) formate is an inorganic compound with the chemical formula Co(HCO 2) 2 (or Co(HCOO) 2). [2] It typically exists as a dihydrate (Co(HCO 2) 2 •2H 2 O) in which it forms a 3D metal–organic framework structure and is known as Co-MOF. [3] Cobalt(II) formate is a red crystalline solid and is soluble in water. It can be very hazardous ...
