Description:
Copper sulfate, with the CAS number 7758-98-7, is an inorganic compound that appears as a blue crystalline solid, commonly known for its vibrant color. It is composed of copper, sulfur, and oxygen, with the chemical formula CuSO₄. This compound is highly soluble in water, forming a blue solution, and is hygroscopic, meaning it can absorb moisture from the air. Copper sulfate is widely used in various applications, including agriculture as a fungicide and herbicide, in the manufacturing of pigments, and in chemical processes. It also serves as a laboratory reagent and is utilized in electroplating and as a root killer in sewer systems. The anhydrous form of copper sulfate is white, while the pentahydrate form, which is more commonly encountered, contains five water molecules and is often referred to as blue vitriol. Safety precautions are necessary when handling copper sulfate, as it can be toxic and irritating to skin and eyes.
