Sell copper sulfate (CuSO4)

详情

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".
