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]
Crystals of hydrated copper(II) sulfate consist of [Cu(H 2 O) 4] 2+ centers linked to SO 2− 4 ions. Copper is surrounded by six oxygen atoms, provided by two different sulfate groups and four molecules of water. A fifth water resides elsewhere in the framework but does not bind directly to copper.

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).
A Many websites state that black vitriol "is a mixture of iron sulfate and iron sulfite", but none give a reference of any sort. The book, Chemistry, Inorganic & Organic, with Experiments, by Bloxam [4] is a published, reliable reference for the composition of black vitriol, and it states on page 513, "The formula of black vitriol may be written [CuMgFeMnCoNi]SO 4 ·7H 2 O, the six isomorphous ...
Basic copper carbonate is a chemical compound, more properly called copper(II) carbonate hydroxide. It can be classified as a coordination polymer or a salt. It consists of copper(II) bonded to carbonate and hydroxide with formula Cu 2 (CO 3)(OH) 2. It is a green solid that occurs in nature as the mineral malachite.
Copper hydride is an inorganic compound with the chemical formula CuH n where n ~ 0.95. [3] It is a red solid, rarely isolated as a pure composition, that decomposes to the elements. [ 4 ] Copper hydride is mainly produced as a reducing agent in organic synthesis and as a precursor to various catalysts.
Tetraamminecopper(II) sulfate monohydrate, or more precisely tetraammineaquacopper(II) sulfate, is the salt with the formula [Cu(N H 3) 4]S O 4 ·H 2 O, or more precisely [Cu(NH 3) 4 (H 2 O)]SO 4. This dark blue to purple solid is a sulfuric acid salt of the metal complex [Cu(NH 3 ) 4 (H 2 O)] 2+ (tetraammineaquacopper(II) cation ).
The heptahydrate is isostructural with ferrous sulfate heptahydrate. The solid consists of [Zn(H 2 O) 6] 2+ ions interacting with sulfate and one water of crystallization by hydrogen bonds. Anhydrous zinc sulfate is isomorphous with anhydrous copper(II) sulfate. It exists as the mineral zincosite. [15] A monohydrate is known. [16]
