kopparsulfatpentahydrat

Kopparsulfatpentahydrat, also known as copper(II) sulfate pentahydrate, is an inorganic compound with the chemical formula CuSO4·5H2O. It is the most common form of copper sulfate. In its pure form, it appears as bright blue crystalline solid. The compound is readily soluble in water, forming an aqueous solution. It is also soluble in methanol but less so in ethanol.

Kopparsulfatpentahydrat is widely used in various applications. In agriculture, it serves as a fungicide, algaecide, and pesticide. It is also used as a mordant in dyeing textiles and in the preparation of pigments. Historically, it has been employed in electroplating baths and as an analytical reagent in laboratories. It is also found as a component in some animal feed supplements to prevent copper deficiency.

When heated, kopparsulfatpentahydrat loses its water of hydration. Upon heating to around 100 degrees Celsius, it transforms into anhydrous copper(II) sulfate, CuSO4, which is a white powder. Further heating can lead to decomposition. The compound should be handled with care as it can be irritating to skin and eyes and is toxic if ingested.
