CuSO4n

CuSO4n, also known as copper(II) sulfate, is a chemical compound with the formula CuSO4. It is a blue crystalline solid that is highly soluble in water. Copper(II) sulfate is commonly used in various industrial and laboratory applications due to its properties.

In industrial settings, CuSO4n is primarily used as a fungicide and algaecide in agriculture. It is also employed in the production of other copper compounds and as a mordant in textile dyeing. In the laboratory, it serves as a source of copper ions and is used in various chemical reactions and experiments.

Copper(II) sulfate is prepared by dissolving copper metal or copper oxide in sulfuric acid. The compound can be crystallized from its aqueous solutions, resulting in the blue crystalline form. It is stable under normal conditions but decomposes upon heating, releasing toxic fumes of sulfur dioxide and copper(II) oxide.

The compound is toxic if ingested or inhaled, and contact with the skin or eyes can cause irritation. Proper handling and disposal procedures should be followed when working with copper(II) sulfate to ensure safety.
