2. Copper(II) sulfate - Wikipedia

   en.wikipedia.org/wiki/Copper(II)_sulfate

   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]

3. Chalcanthite - Wikipedia

   en.wikipedia.org/wiki/Chalcanthite

   Chalcanthite (from Ancient Greek χάλκανθον (khálkanthon), from χαλκός (khalkós) ' copper ' and ἄνθος (ánthos) ' flower, bloom ') is a richly colored blue-green water-soluble sulfate mineral CuSO 4 ·5H 2 O. It is commonly found in the late-stage oxidation zones of copper deposits. Due to its ready solubility ...

4. Copper(I) sulfate - Wikipedia

   en.wikipedia.org/wiki/Copper(I)_sulfate

   Copper(I) sulfate, also known as cuprous sulfate, is an inorganic compound with the chemical formula Cu 2 SO 4. It is a white solid, in contrast to copper(II) sulfate, which is blue in hydrous form. Compared to the commonly available reagent, copper(II) sulfate, copper(I) sulfate is unstable and not readily available. [1]

5. Brochantite - Wikipedia

   en.wikipedia.org/wiki/Brochantite

   Brochantite is a sulfate mineral, one of a number of cupric sulfates.Its chemical formula is Cu 4 SO 4 (OH) 6. [2] [3] [4] Formed in arid climates or in rapidly oxidizing copper sulfide deposits, it was named by Armand Lévy for his fellow Frenchman, geologist and mineralogist A. J. M. Brochant de Villiers.

6. Water of crystallization - Wikipedia

   en.wikipedia.org/wiki/Water_of_crystallization

   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.

7. Copper sulfate - Wikipedia

   en.wikipedia.org/wiki/Copper_sulfate

   Copper sulfate may refer to: Copper(II) sulfate, CuSO 4, a common, greenish blue compound used as a fungicide and herbicide; Copper(I) sulfate, Cu 2 SO 4, an unstable ...
