Nickel(II) hydroxide(CAS: 12054-48-7)

Nickel(II) hydroxide, also known as basic nickel carbonate or nickelous hydroxide, is a chemical compound with the chemical formula Ni(OH)2. It is a white, crystalline solid that is slightly soluble in water and exhibits basic properties due to the presence of hydroxide ions.

Nickel(II) hydroxide is primarily used in the production of nickel-cadmium and nickel-metal hydride rechargeable batteries. It is also utilized in coatings, pigments, and as a raw material for other nickel compounds. Additionally, it is employed in the development of certain catalysts and as an absorbent in some industrial processes.

Nickel(II) hydroxide can be toxic if inhaled or ingested, and prolonged skin contact can cause irritation. It is classified as a skin sensitiser and a respiratory sensitiser. Proper handling precautions include wearing gloves, goggles, and a respirator. It should be stored in a well-ventilated area and handled in a fume hood. Disposal should comply with local regulations to avoid environmental contamination.

Nickel(II) hydroxide should be stored in a cool, dry place away from direct sunlight and heat sources. It should be kept in a tightly sealed container to prevent moisture absorption and degradation. Handle with care to avoid spills and ensure proper ventilation during storage and use. Adequate fire-fighting equipment should be available in the storage area in case of emergencies.
