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]
Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4.It forms hydrates CuSO 4 ·nH 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]

Magenta coloured CoCl 2 ·6H 2 O. Many halides of cobalt(II) are known.e cobalt(II) fluoride (CoF 2) which is a pink solid, cobalt(II) chloride (CoCl 2) which is a blue solid, cobalt(II) bromide (CoBr 2) which is a green solid, and cobalt(II) iodide (CoI 2) which is a blue-black solid.
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).
Cuprous sulfate is produced by the reaction of copper metal with sulfuric acid at 200 °C: [3]. 2 Cu + 2 H 2 SO 4 → Cu 2 SO 4 + SO 2 + 2 H 2 O. Cu 2 SO 4 can also be synthesized by the action of dimethyl sulfate on cuprous oxide: [4]
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).
The chemistry of sulfur is largely covalent in nature, noting it can form ionic sulfides with highly electropositive metals. The common oxide of sulfur (SO 3) is strongly acidic. Selenium. Selenium is a metallic-looking, moderately reactive [8] solid with a density of 4.81 g/cm 3 and is soft (MH 2.0) and brittle. It melts at 221 °C to a black ...
