kuparisulfaatit

Kuparisulfaatit are a group of chemical compounds with the general formula CuSO4.xH2O. The most common and well-known form is copper(II) sulfate pentahydrate, CuSO4·5H2O, which is a vivid blue crystalline solid. This compound is often referred to simply as copper sulfate.

Copper sulfate has a variety of applications. In agriculture, it is used as a fungicide and algaecide to control diseases in crops and to prevent algal blooms in ponds and lakes. It is also a component of some herbicides. In industry, it serves as a mordant in dyeing textiles, an electrolyte in copper plating, and a precursor for the production of other copper compounds. Historically, copper sulfate was used in medicine as an astringent and emetic, though these uses are now largely obsolete due to toxicity concerns.

Copper sulfate pentahydrate is formed when copper(II) sulfate anhydrous, CuSO4, which is a white powder, absorbs water molecules. The anhydrous form readily dissolves in water, forming a solution that also exhibits a blue color due to the presence of hydrated copper ions. The solubility of copper sulfate in water increases with temperature.

Exposure to copper sulfate can be irritating to the skin, eyes, and respiratory tract. Ingestion can lead to gastrointestinal distress, and in larger doses, it can cause liver and kidney damage. Therefore, proper handling procedures and safety precautions are necessary when working with these compounds.
