Physical and Chemical Properties
Nickel acetate is an odorless, green solid with a powdery consistency. According to the Material Safety Data Sheet, it is stable under standard temperatures and pressures. It does not have a melting point, but instead decomposes under intense heat. It is not flammable. Nickel acetate is highly reactive with acids and strong oxidizing agents.
Use in Electroplating
Nickel acetate is frequently used to electroplate other metal objects. Electroplating is the application of a metal coating to a surface, usually to add a layer of protection. The metal coating may provide the object with properties that the uncoated object would not otherwise possess. Most often, the desired property is resistance to corrosion or abrasion. Electroplating may also give an object thickness, lubricity or an aesthetically appealing shine.
Use as a Mordant
Because nickel(II) is a cation, nickel acetate is also used as a mordant. Mordants are substances that enable paints, dyes, or stains to stay put. Nickel acetate is frequently used as a mordant in the textile industry to keep dyes on the fabric's surface. To accomplish this, a cation forms covalent bonds with both the fabric material and the dye.
Potential Hazards
According to a data sheet constructed by the University of Akron's Department of Chemistry, nickel ranks in toxicity class IV, which is the lowest-ranking class. Still, it is a potential carcinogen, and prolonged exposure may cause dizziness, irritation of the respiratory canals and weakness. It is important that those handling nickel acetate take the necessary precautions, including wearing gloves and a face shield. While nickel acetate is not flammable, it may be combustible at high temperatures. Fires involving nickel or nickel compounds may release toxic vapors.
