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]

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]
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.

No mineral of the ideal Cu(NO 3) formula, or the hydrates, are known. Likasite, Cu 3 (NO 3)(OH) 5 ·2H 2 O and buttgenbachite, Cu 19 (NO 3) 2 (OH) 32 Cl 4 ·2H 2 O are related minerals. [21] [22] Natural basic copper nitrates include the rare minerals gerhardtite and rouaite, both being polymorphs of Cu 2 (NO 3)(OH) 3.
Copper(II) hydroxide is the hydroxide of copper with the chemical formula of Cu(OH) 2.It is a pale greenish blue or bluish green solid. Some forms of copper(II) hydroxide are sold as "stabilized" copper(II) hydroxide, although they likely consist of a mixture of copper(II) carbonate and hydroxide.
