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 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 ...

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
Cobalt(II) perchlorate hexahydrate is produced by reacting cobalt metal or cobalt(II) carbonate with perchloric acid, followed by the evaporation of the solution: [1] CoCO 3 + 2 HClO 4 → Co(ClO 4) 2 + H 2 O + CO 2. The anhydrous form cannot be produced from the hexahydrate by heating, as it instead decomposes to cobalt(II,III) oxide at 170 °C.
The compound is prepared by oxidation of cobalt(II) salts in the presence of sodium nitrite: [3] 4 [Co(H 2 O) 6 ](NO 3 ) 2 + O 2 + 24 NaNO 2 → 4 Na 3 [Co(NO 2 ) 6 ] + 8 NaNO 3 + 4 NaOH + 22 H 2 O Application for analysis of potassium
Cobalt(II,III) oxide is an inorganic compound with the formula Co 3 O 4. It is one of two well characterized cobalt oxides. It is a black antiferromagnetic solid. As a mixed valence compound, its formula is sometimes written as Co II Co III 2 O 4 and sometimes as CoO•Co 2 O 3. [4]
