Cobalt(II) sulfate is any of the inorganic compounds with the formula CoSO4(H2O)x. 
Usually cobalt sulfate refers to the hexa- or heptahydrates CoSO4.6H2O or CoSO4.7H2O, respectively.
The heptahydrate is a red solid that is soluble in water and methanol. 
Since cobalt(II) has an odd number of electrons, Cobalt Sulfate salts are paramagnetic.

Cobalt Sulfate is a moderately water and acid soluble Cobalt source for uses compatible with sulfates. 
Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. 
Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. 
Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions. 
Metallic ions can also be dispersed utilizing suspended or coated nanoparticles and deposited utilizing sputtering targets and evaporation materials for uses such as solar cells and fuel cells. 
Cobalt Sulfate is generally immediately available in most volumes. 
High purity, submicron and nanopowder forms may be considered.

Cobalt Sulfate is an odorless monoclinic crystalline solid that is soluble in water, liquifying slowly around 100 °C and becoming anhydrous at 250 °C.

Cobalt sulfate, also known as cobalt brown or COSO4, belongs to the class of inorganic compounds known as transition metal sulfates. 
These are inorganic compounds in which the largest oxoanion is sulfate, and in which the heaviest atom not in an oxoanion is a transition metal. 
Cobalt sulfate is an extremely strong acidic compound (based on its pKa). 

Cobalt Sulphate is vital for ruminant animals, ie cattle, sheep, Goats. 
Cobalt Sulphate helps the the enzymes of the gut by aiding in the production of vitamin B12. 
Vitamin B12 is vital for the gut microbes to convert the stomach contents into digestible matter that is used for energy and weight gain. 
Therefore, if cobalt is in short supply, this will restrict the manufacture of vitamin B12 and this will result in the lambs not being able to properly digest their food. 
Cobalt Sulphate can help with keep cobalt levels up in the animals by mixing Cobalt Sulfate with water and giving Cobalt Sulfate as aan oral drench. 

Cobalt sulfate has been detected, but not quantified in, alcoholic beverages. 
This could make cobalt sulfate a potential biomarker for the consumption of these foods. 
Cobalt sulfate is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound.

Preparation, and structure
Cobalt Sulfate forms by the reaction of metallic cobalt, Cobalt Sulfates oxide, hydroxide, or carbonate with aqueous sulfuric acid:
Co + H2SO4 + 7 H2O → CoSO4(H2O)7 + H2
CoO + H2SO4 + 6 H2O → CoSO4(H2O)7

The heptahydrate is only stable at humidity >70% at room temperature, otherwise Cobalt Sulfate converts to the hexahydrate.
The hexahydrate converts to the monohydrate and the anhydrous forms at 100 and 250 °C, respectively.
CoSO4(H2O)7 → CoSO4(H2O)6 + H2O
CoSO4(H2O)6 → CoSO4(H2O) + 5 H2O
CoSO4(H2O) → CoSO4 + H2O

The hexahydrate is a metal aquo complex consisting of octahedral [Co(H2O)6]2+ ions associated with sulfate anions.
The monoclinic heptahydrate has also been characterized by X-ray crystallography. 
Cobalt Sulfate also features [Co(H2O)6]2+ octahedra as well as one water of crystallization.

Uses of Cobalt Sulfate:
Cobalt(II) sulfate is used in storage batteries and electroplating baths for cobalt. 
Cobalt Sulfate also is used as a dryer for lithographic inks; in pigments for decorating porcelains; in ceramics, glazes and enamels to protect from discoloring; and as a additive to soils.

Preparation of Cobalt Sulfate:
Cobalt(II) sulfate is prepared by dissolving cobalt(II) oxide, hydroxide or carbonate in dilute sulfuric acid, followed by crystallization:
CoO + H2SO4 → CoSO4 + H2O
Co(OH)2 + H2SO4 → CoSO4 + 2H2O
CoCO3 + H2SO4 → CoSO4 + CO2 + H2O
Crystallization yields the commercial product, pink heptahydrate. 
Further oxidation of this salt in dilute H2SO4 with ozone or fluorine produces hydrated cobalt(III) sulfate, Co2(SO4)3•18H2O. 
This blue octadecahydrate, Co2(SO4)3•18H2O also is obtained by electrolytic oxidation of cobalt(II) chloride or any cobalt(II) salt solution in 8M sulfuric acid.

Description of Cobalt Sulfate:
The blue, crystalline hydrate Co2(SO4)3.18H2O is prepared by the oxidation of cobalt(II) sulphate in 8N sulphuric acid either electrolytically or chemically with ozone or fluorine. 
Cobalt Sulfate is stable in the dry state, but is decomposed by water with evolution of oxygen; Cobalt Sulfate is fairly stable in solution in dilute sulphuric acid. 
Cobalt(III) alums MCo(SO4)2.12H2O (M = K, Rb, Cs or NH4) can be isolated as blue crystals from the mixed cooler solutions of the two sulphates in dilute sulphuric acid. 
The potassium alum is diamagnetic, the rubidium salt has a magnetic moment less than 1 B.M. and the ammonium alum has a moment of 2.1 B.M. at 304°K. 
The hydrated sulphate also has a small positive magnetic susceptibility. 
The sulphate is believed like the alums to contain the [Co(H2O)6]3+ ion.

Physical
Cobalt(II) sulfate is a red (anhydrous, monohydrate) or pink (hexa-, heptahydrate) crystalline solid, soluble in water, with the hydrated form more soluble in methanol than the anhydrous one. 
Cobalt Sulfate also displays moderate solubility in ethanol, but insoluble in non-polar solvents. 
Cobalt Sulfate decomposes when heated above 735 °C.

Cobalt sulphate is the most popular form of cobalt for use in fertilisers as well as animal health formulations. 
Cobalt is essential to all ruminants who have the ability to convert this form of cobalt directly to vitamin B12. 
Without adequate B12 levels within the digestive system cattle will suffer severe ill thrift. 
Subclinical deficiencies can commonly cause issues around conception, maintenance of live weight, as well as production losses.

What is Cobalt ?
Cobalt is a hard, lustrous and a grey metal with symbol Co and atomic number 27. 
Cobalt is a transition metal with a close packed hexagonal (CPH) crystal structure at room temperature.
The name Cobalt was derived from the German word ‘Kobold’, meaning evil spirits. 
The interest in cobalt’s uses goes back to 2000 B.C. when cobalt was used by Egyptian artisans as a coloring agent.

Cobalt-based colors and pigments are in use since ancient times for making jewelry and paints. 
Miners have long used the name ‘kobold’ ore for some minerals.

Cobalt is an essential trace element for all multi-cellular organisms as the active center of coenzymes called cobalamins. 
These include vitamin B12 that is essential for mammals. 
Cobalt is also an active nutrient for bacteria, algae, and fungi, and may be a necessary nutrient for all life.

General Properties:
Cobalt is one of the world’s essential elements. 
Cobalt Sulfate has many strategic and irreplaceable industrial uses but Cobalt Sulfate is also a central component of Vitamin B12 that Cobalt Sulfate is vital. 
Cobalt Sulfate has a high melting point and retains Cobalt Sulfates strength to a high temperature.

Preparation methods of cobalt sulfate
Method one
Cobalt is dissolved in mixed acids of sulfuric acid and nitric acid (about 4:1). 
When the mass fraction reaches 22%-23%, heat directly to the boiling point with steam.
When the mass fraction reaches 43%-44%, the product can be crystallized for 3-4 days and the finished product is obtained by centrifugation. 
The mother liquor mass fraction exceeds 30%, adding 35%-36% sulfuric acid solution and a small amount of nitric acid to dissolve the cobalt.
3Co+2HNO3+3H2SO4→3CoSO4+2NO2↑+4H2O
2NO+O2→2NO2↑

Method two
Dissolving cobalt oxide with sulfuric acid, the solution is evaporated, crystallized, centrifuged and dehydrated, cobalt sulfate is made.
CoO+H2SO4→CoSO4+H2O
