rézszulfát

Rézszulfát, also known as copper sulfate, is an inorganic chemical compound with the formula CuSO4. It commonly exists as a blue crystalline solid, which is the pentahydrate form (CuSO4·5H2O). In its anhydrous form, it appears as a white powder. Rézszulfát is soluble in water and methanol, forming an acidic solution.

Historically, copper sulfate has been known by various names, including blue vitriol and blue stone. It is produced industrially by reacting copper metal with an aqueous solution of sulfuric acid and air. Another method involves dissolving copper(II) oxide or carbonate in sulfuric acid.

Rézszulfát has a wide range of applications. In agriculture, it is used as a fungicide to control fungal diseases on plants and as an algaecide in ponds and water treatment. It also serves as a feed additive for livestock. In laboratories, it is used as a reagent and in electroplating processes. It finds use in pyrotechnics for producing blue colors and in analytical chemistry. The compound is also used in some educational demonstrations due to its distinctive blue color.

Despite its utility, rézszulfát is toxic and should be handled with care. Ingestion can cause gastrointestinal distress, and prolonged skin contact can lead to irritation. Environmental release should be minimized due to its toxicity to aquatic life.
