Nickel(II) acetate
Encyclopedia
Nickel acetate is an inorganic compound of nickel
and acetic acid
. This inorganic compound is usually found as the tetrahydrate. It is used for electroplating
.
It can be made by reacting nickel with Acetic acid or with nickel(II) carbonate
.
The green tetrahydrate has been determined by X-ray crystallography
to be octahedral about the central nickel atom, coordinated by four water molecules and two acetate fragments. It may be dehydrated in vacuo, by reaction with acetic anhydride
, or by heat.
Nickel
Nickel is a chemical element with the chemical symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile...
and acetic acid
Acetic acid
Acetic acid is an organic compound with the chemical formula CH3CO2H . It is a colourless liquid that when undiluted is also called glacial acetic acid. Acetic acid is the main component of vinegar , and has a distinctive sour taste and pungent smell...

Electroplating
Electroplating is a plating process in which metal ions in a solution are moved by an electric field to coat an electrode. The process uses electrical current to reduce cations of a desired material from a solution and coat a conductive object with a thin layer of the material, such as a metal...

Nickel(II) carbonate
Nickel carbonate describes one or a mixture of inorganic compounds containing nickel and carbonate. From the industrial perspective, the most important nickel carbonate is basic nickel carbonate with the formula Ni4CO364. Simpler carbonates, ones more likely encountered in the laboratory, are NiCO3...

- Ni + CH3COOH → C4H6NiO4 + H2O
- NiCO3 + CH3COOH → C4H6NiO4 + CO2 + H2O
The green tetrahydrate has been determined by X-ray crystallography
X-ray crystallography
X-ray crystallography is a method of determining the arrangement of atoms within a crystal, in which a beam of X-rays strikes a crystal and causes the beam of light to spread into many specific directions. From the angles and intensities of these diffracted beams, a crystallographer can produce a...

Acetic anhydride
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula 2O. Commonly abbreviated Ac2O, it is the simplest isolatable acid anhydride and is a widely used reagent in organic synthesis...
