Cupric sulfate

Cupric sulfate, also known as copper(II) sulfate, is a chemical compound with the formula CuSO4. It is a common salt of copper, and has been used for a variety of purposes throughout history.

History

The use of cupric sulfate dates back to ancient times, when it was used in alchemy and early medical treatments. It was also used in the process of dyeing fabrics due to its vibrant blue color.

Properties

Cupric sulfate is a blue, crystalline solid at room temperature. It is highly soluble in water, and its solutions are acidic due to the presence of sulfate ions. The compound is also soluble in methanol and slightly soluble in ethanol.

Production

Cupric sulfate is produced industrially by treating copper metal with hot concentrated sulfuric acid or its oxides with dilute sulfuric acid. The resulting product is then crystallized to produce a blue crystalline solid.

Uses

Cupric sulfate has a wide range of uses. It is used in agriculture as a fungicide, in the textile industry for dyeing and in the production of other copper compounds. It is also used in laboratories for demonstrating anhydrous conditions and in schools for growing crystals.

Safety

Exposure to cupric sulfate can cause irritation to the eyes, skin, and respiratory tract. It is also toxic if ingested or inhaled in large quantities. Proper safety measures should be taken when handling this compound.
