Chemistry

The Molecular formula of Copper sulfate(18939-61-2): CuSO4
The Molar mass of Copper sulfate(18939-61-2): 159.61 g/mol
The Structure:
Appearance: gray-white powder
Density: 3.603 g/cm3  
Solubility in water: 31.6 g/100 ml (0 °C)
Solubility: insoluble in ethanol 
Copper sulfate(18939-61-2) is the chemical compound with the formula CuSO4. Copper sulfate (18939-61-2) is the most important compound of copper. 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  and boothite. Archaic names for copper sulfate are "blue vitriol" and "bluestone".

Uses

A mixture of copper sulfate(18939-61-2) and ammonium carbonate used in horticulture to prevent damping off in seedlings. Its use as a herbicide is not agricultural, but instead for control of invasive exotic aquatic plants and the roots of other invasive plants near various pipes that contain water.
Because of its poisonous nature, copper sulfate(18939-61-2) is used in the fungicide Bordeaux mixture, which is formed upon mixing copper sulfate solution with milk of lime and is added to water reservoirs to kill algae. It is also employed in electroplating and used as a mordant, germicide, and agent in engraving.

Production

Copper sulfate(18939-61-2) is usually purchased and not prepared in the laboratory. It can be made by the action of sulfuric acid on a variety of copper(II) compounds, for example copper(II) oxide; this oxide can be generated with the addition of hydrogen peroxide to the acid. It may also be prepared by electrolyzing sulfuric acid, using copper electrodes
