CAS number: 7758-98-7 (anhydrous); 7758-99-8 (pentahydrate)
EC number: 231-847-6
Molecular formula: CuSO4 or CuSO4.5H2O
Molecular weight: 159.62 g/mol (anhydrous); 249.70 g/mol (pentahydrate)

Copper (II) sulfate, also known as cupric sulfate or copper sulphate, is the chemical compound with the chemical formula CuSO4. This salt exists as a series of compounds that differ in their degree of hydration. The anhydrous form is a pale green or gray-white powder, whereas the pentahydrate (CuSO4·5H2O), the most commonly encountered salt, is bright blue. Copper sulfate exothermically dissolves in water to give the aquo complex [Cu(H2O)6]2+, which has octahedral molecular geometry and is paramagnetic. Other names for copper (II) sulfate are "blue vitriol" and "bluestone".

Copper (II) sulfate pentahydrate decomposes before melting at 150°C, losing two water molecules at 63°C, followed by two more at 109 °C and the final water molecule at 200°C.

Copper sulphate or Cupric sulfate is used in:
Agricultural chemicals
Feeds
Germicides - in the textile and leather industries
Pigments
Electric batteries
Reagent in analytical chemistry
Medicine
Wood preservative
For engraving and lithography
Mining and petroleum industries
Synthetic rubber
Steel manufacture
Asphalts manufacture
The anhydrous salt is used as a dehydrating agent
Copper sulfate is employed in ceramics for metallic coloration
and so on.

CHARACTERS
Appearance: Blue, crystalline powder or transparent, blue crystals.
Solubility: Freely soluble in water, soluble in methanol, practically insoluble in ethanol (96 per cent).

IDENTIFICATION
A. Add several drops of dilute ammonia to 1 ml of solution S (see Tests). A blue precipitate is formed. On further addition of dilute ammonia the precipitate dissolves and a dark blue colour is produced.
B. Loss on drying (see Tests).
C. Dilute 1 ml of solution S to 5 ml with water. The solution gives reaction of sulphates.

TESTS
Solution S: Dissolve 5 g in water and dilute to 100 ml with the same solvent.
Appearance of solution: Solution S is clear.
Chlorides: Maximum 100 ppm.
Iron: Maximum 1.00 × 102 ppm.
Atomic absorption spectrometry: To meet the requirement.
Lead: Maximum 50.0 ppm.
Loss on drying: 35.0 per cent to 36.5 per cent, determined on 0.500 g by drying in an oven at 250 ± 10C.
