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).

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]
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.
Although many textbooks (e.g. [7]) give the mixed valence formula (Cu +) 2 (Cu 2+)(S 2−)(S 2) 2− for CuS, X-ray photoelectron spectroscopic data give strong evidence that, in terms of the simple oxidation state formalism, all the known copper sulfides should be considered as purely monovalent copper compounds, and more appropriate formulae ...
