2.284 g/cm3 (pentahydrate)
Melting point------110 ° C (4H2O)
150 ° C (423 K) (5H2O)
< 650 ° C decomp.
Solubility in water------31.6 g/100 ml (0 ° C)
Solubility: Anhydrous insoluble in ethanol
Pentahydrate soluble in methanol and ethanol
Copper sulfate is the chemical compound with the 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, the most commonly encountered salt, is bright blue. The anhydrous form occurs as a rare mineral known as chalcocyanite. The hydrated copper sulfate occurs in nature as chalcanthite (pentahydrate), and two more rare ones: Bonattite (trihydrate) and boothite (heptahydrate). Archaic names for copper sulfate are "blue vitriol" and "bluestone".
