Nickel(II) acetate
Nickel(II) acetate is a chemical compound with the formula Ni(CH3COO)2, or Ni(C2H3O2)2. It exists in both anhydrous and hydrated forms. The most common form is the tetrahydrate, Ni(CH3COO)2·4H2O. It is a green crystalline solid.
Nickel(II) acetate is synthesized by reacting nickel(II) carbonate with acetic acid. It is soluble in water, forming a green solution. It is also soluble in alcohol.
Nickel(II) acetate is primarily used as a precursor to other nickel compounds. It serves as a catalyst in various organic reactions, including oxidation reactions. It is also utilized in electroplating and dyeing processes. Furthermore, it finds application as a mordant in textiles, aiding in the fixation of dyes.
The compound is considered a hazardous material and should be handled with care, as nickel compounds are generally known to be carcinogenic. Exposure can occur through inhalation, ingestion, skin contact, and eye contact. Proper personal protective equipment, such as gloves, eye protection, and a respirator, should be worn when handling nickel(II) acetate.
