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]
In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.
4 CuSO 4 + 6 NH 3 + 6H 2 O → Cu 4 SO 4 (OH) 6 + 3 (NH 4) 2 SO 4 Cu 4 SO 4 (OH) 6 + 2 NaOH → 4 Cu(OH) 2 + Na 2 SO 4. Alternatively, copper hydroxide is readily made by electrolysis of water (containing a little electrolyte such as sodium sulfate or magnesium sulfate) with a copper anode: Cu + 2OH − → Cu(OH) 2 + 2e −

The terms "molecular mass", "molecular weight", and "molar mass" may be used interchangeably in less formal contexts where unit- and quantity-correctness is not needed. The molecular mass is more commonly used when referring to the mass of a single or specific well-defined molecule and less commonly than molecular weight when referring to a ...

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]
