Nickel(II) 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.
- Ni + CH3COOH → C4H6NiO4 + H2O
- NiCO3 + CH3COOH → C4H6NiO4 + CO2 + H2O
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.[1] It may be dehydrated in vacuo, by reaction with acetic anhydride,[2] or by heat.[3]
[edit] Safety
Nickel salts are carcinogenic and irritate the skin.
