Copper(II) sulfate is a chemical compound renowned for its vibrant blue hue when hydrated and its essential roles across various sectors. While the anhydrous form, typically a white powder, is crucial for specific applications, the pentahydrate form (CuSO4·5H2O) is perhaps the most recognized, often referred to as blue vitriol. NINGBO INNO PHARMCHEM CO.,LTD. offers both forms, enabling a deeper understanding of their distinct properties and the fascinating chemistry that links them.

The key difference lies in the presence of water molecules. Anhydrous Copper(II) sulfate (CAS 7758-98-7) contains no water of crystallization, which makes it a highly effective drying agent and a preferred catalyst in certain reactions where water can interfere. Its white, powdery appearance is a hallmark of its dehydrated state.

In contrast, Copper(II) sulfate pentahydrate (CAS 7758-99-8) incorporates five water molecules per formula unit of CuSO4. These water molecules are integrated into the crystal structure, giving the compound its characteristic bright blue color and crystalline form. This hydrated form is widely used in educational settings to demonstrate crystallization, the concept of hydration, and the color changes associated with it. The chemistry of copper sulfate hydrates is a fundamental topic in inorganic chemistry.

A remarkable aspect of Copper(II) sulfate chemistry is the reversible nature of its hydration. When the blue pentahydrate is heated, it loses its water molecules, transforming into the white anhydrous form. Conversely, when the anhydrous white powder is exposed to water, it readily absorbs moisture and reverts back to the blue pentahydrate. This simple yet illustrative chemical reaction is often used to teach about chemical equilibrium and water's role in chemical structures.

NINGBO INNO PHARMCHEM CO.,LTD. is a trusted supplier of chemicals, providing high-quality Copper(II) sulfate in both anhydrous and pentahydrate forms. Our commitment to purity and consistency ensures that these materials perform as expected, whether used in industrial processes, agricultural applications, or laboratory experiments. For those looking to purchase copper sulfate, understanding these forms is key to selecting the right product.

In conclusion, the study of Copper(II) sulfate hydrates offers valuable insights into chemical principles. From the practical applications of the anhydrous form as a catalyst and drying agent to the educational significance of the blue pentahydrate, this compound continues to be a subject of interest and utility in chemistry.
