Cas no 7758-99-8 (Copper(II) sulfate pentahydrate)
Copper(II) sulfate pentahydrate (CuSO?·5H?O) is a blue crystalline solid widely used in industrial and laboratory applications. Its high solubility in water and stability under standard conditions make it a reliable reagent for analytical chemistry, electroplating, and agricultural fungicides. The pentahydrate form ensures consistent hydration, facilitating precise formulations in chemical synthesis and educational demonstrations. As a source of copper ions, it is essential in catalysis, metal treatment, and electrolyte solutions. Its distinct color also serves as an indicator in qualitative analysis. The compound is handled with care due to its toxicity but remains valued for its versatility and effectiveness in diverse chemical processes.
