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) chloride is an inorganic compound, a salt of cobalt and chlorine, with the formula CoCl 2.The compound forms several hydrates CoCl 2 ·n H 2 O, for n = 1, 2, 6, and 9. . Claims of the formation of tri- and tetrahydrates have not been confirmed
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) thiocyanate is an inorganic compound with the formula Co(SCN) 2. [1] The anhydrous compound is a coordination polymer with a layered structure. The trihydrate, Co(SCN) 2 (H 2 O) 3, is a isothiocyanate complex used in the cobalt thiocyanate test (or Scott test) for detecting cocaine. The test has been responsible for widespread false ...
Its permethylated analogue decamethylcobaltocene (Co(C 5 Me 5) 2) is an especially powerful reducing agent, due to inductive donation of electron density from the 10 methyl groups, prompting the cobalt to give up its "extra" electron even more so. These two compounds are rare examples of reductants that dissolve in non-polar organic solvents.
