Copper sulphate pentahydrate is a fungicide and pesticide. However, some fungi are capable of adapting to elevated levels of copper ions. Mixed with lime it is called Bordeaux mixture and used to control fungus on grapes, melons, and other berries. Another application is Cheshunt compound a mixture of copper sulfate and ammonium carbonate used in horticulture to prevent damping off in seedlings.

A dilute solution of copper sulphate is used to treat aquarium fish for parasitic infections, and is also used to remove snails from aquariums. Copper ions are highly toxic to fish, so care must be taken with the dosage. Most species of algae can be controlled with very low concentrations of copper sulfate. Copper sulphate inhibits growth of bacteria such as Escherichia coli. It is also used as a wood preservative apart from its use in electroplating. It can also be used as a mordant in vegetable dyeing.

Copper Sulphate Pentahydrate BP Grade Ph Eur

CuSO4-5H2O — 249.7 — 7758-99-8

Content: 99.0 per cent to 101.0 per cent.

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

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.

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 ± 10 °C.
