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 ...
Moorhouseite is a rare mineral with the formula CoSO 4 •6H 2 O, a naturally occurring cobalt(II) sulfate hexahydrate. It is the lower-hydrate-equivalent of bieberite (heptahydrate) and aplowite (hexahydrate). It is also hydrated equivalent of cobaltkieserite. It occurs together with moorhouseite within efflorescences found in the Magnet Cove ...
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]
The compound is usually prepared by mixing cobalt(II) chloride, dimethylglyoxime and pyridine in an ethanolic solution. This process afford the cobaloxime(II), which is subsequently oxidized by the oxygen in air: [3] 4 CoCl 2 •6H 2 O + 8 dmgH 2 + 8 py + O 2 → 4 ClCo(dmgH) 2 py + 4 py•HCl + 14 H 2 O
Cobalt sulfides occur widely as minerals, comprising major sources of all cobalt compounds. Binary cobalt sulfide minerals include the cattierite (CoS 2) and linnaeite (Co 3 S 4). CoS 2 (see image in table) is isostructural with iron pyrite, featuring disulfide groups, i.e. Co 2+ S 2 2−. Linnaeite, also rare, adopts the spinel motif. [2]
Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4. It forms hydrates CuSO 4 · n H 2 O , where n can range from 1 to 7. The pentahydrate ( n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate, [ 10 ] while its anhydrous form is white. [ 11 ]
