CuSO4-5H2O --- 249.7 --- 7758-99-8

DEFINITION
Content: 99.0 per cent to 101.0 per cent.

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.
