Copper sulfate pentahydrate

Description:
Copper sulfate pentahydrate, with the CAS number 7758-99-8, is a blue crystalline solid that is commonly encountered in its hydrated form. It consists of copper sulfate (CuSO₄) combined with five water molecules (5H₂O), giving it the chemical formula CuSO₄·5H₂O. This compound is known for its vibrant blue color, which is due to the presence of copper ions. It is highly soluble in water, making it useful in various applications, including agriculture as a fungicide and herbicide, in chemical laboratories as a reagent, and in the production of other copper compounds. The pentahydrate form is stable under normal conditions but can lose water upon heating, transitioning to anhydrous copper sulfate, which is white. Copper sulfate pentahydrate is also known for its hygroscopic properties, meaning it can absorb moisture from the air. Safety precautions should be taken when handling this substance, as it can be harmful if ingested or inhaled, and it may cause skin and eye irritation.
