Nickel Chloride, known industrially by its CAS number 7791-20-0, is a fascinating compound with a range of useful chemical properties that make it indispensable in several industrial processes, most notably electroplating. For professionals in research and development or procurement looking to buy Nickel Chloride, understanding its fundamental characteristics is key to its effective application.

The most common form encountered is Nickel Chloride Hexahydrate (NiCl2·6H2O), which typically appears as green crystals. This hydrated form is preferred for many applications due to its ease of handling and dissolution. A critical chemical property is its solubility. Nickel Chloride Hexahydrate is highly soluble in water, forming a distinct green solution. It also demonstrates good solubility in polar organic solvents like ethanol and is slightly soluble in ether. This broad solubility profile makes it adaptable for various solution-based processes.

In terms of reactivity, Nickel Chloride acts as a source of nickel ions (Ni2+) in aqueous solutions. This property is fundamental to its role in electroplating, where these ions are reduced at the cathode to deposit metallic nickel onto a substrate. It can also participate in various chemical synthesis reactions, acting as a catalyst or reactant in the formation of other nickel compounds. Its hygroscopic nature means it readily absorbs moisture from the air, underscoring the importance of proper storage in tightly sealed containers, as recommended by manufacturers.

The compound's other applications, such as acting as a preservative or an ammonia absorber, stem from its chemical interactions. As a preservative, it can inhibit microbial growth in certain formulations. Its ability to absorb ammonia relates to the formation of coordination complexes with ammonia molecules, a property leveraged in specific gas scrubbing or chemical absorption systems.

When you are ready to purchase Nickel Chloride, selecting a supplier that can provide consistent quality and accurate chemical data is paramount. Manufacturers in China are a primary source for this compound, offering the product with specified purity levels and well-documented chemical properties. Whether you need it for electroplating baths, chemical synthesis, or other industrial uses, ensuring you buy Nickel Chloride from a reputable source guarantees that its inherent chemical properties will perform as expected in your applications.
