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. This hydrated copper sulfate occurs in nature as the mineral called chalcanthite. Archaic names for copper(II) sulfate are "blue vitriol" and "bluestone".
Copper sulfate pentahydrate decomposes before melting, losing four water molecules at 110 .C and all five at 150 .C. At 650 .C, copper sulfate decomposes into copper oxide (CuO) and sulfur trioxide (SO3). When heated in an open flame the crystals are dehydrated and turn grayish-white.
