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]

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).
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.

Copper forms coordination complexes with ligands.In aqueous solution, copper(II) exists as [Cu(H 2 O) 6] 2+This complex exhibits the fastest water exchange rate (speed of water ligands attaching and detaching) for any transition metal aquo complex.
Tetraaminecopper(II) sulfate monohydrate milled Analogous compound with different anion: tetraamminecopper(II) iodide monohydrate. 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.
Currently the article states "The pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue. It exothermically dissolves in water." Dissolving the pentahydrate in water decreases the temperature of the overall solution, i.e. the dissolution is endothermic.
