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 sulfide is the name for chemical compounds with a formula Co x S y. Well-characterized species include minerals with the formulas CoS, CoS 2, Co 3 S 4, and Co 9 S 8. In general, the sulfides of cobalt are black, semiconducting, insoluble in water, and nonstoichiometric. [1]
These hydrates have the chemical formula Co(NO 3) 2 ·nH 2 O, where n = 0, 2, 4, 6. Anhydrous cobalt(II) nitrate adopts a three-dimensional polymeric network structure, with each cobalt(II) atom approximately octahedrally coordinated by six oxygen atoms, each from a different nitrate ion. Each nitrate ion coordinates to three cobalts. [3]

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 ...
