Nickel(II) acetate tetrahydrate Chemical Properties,Uses,Production

Physical Properties

The tetrahydrate is a green crystalline solid; sweet taste; odor of acetic acid; density 1.744 g/cm3; loses water on heating to form a yellow-green powder of anhydrous nickel acetate; decomposes above 250°C; soluble in water, 17g/100mL at 20°C; sparingly soluble in alcohol.


Nickel acetate is used as a catalyst. It also is used as a dye mordant in textiles. Other applications are in electroplating nickel and as a sealer for anodizing aluminum.


Nickel acetate is prepared by reacting nickel hydroxide or nickel carbonate with dilute acetic acid. The tetrahydrate is crystallized from solution.
Ni(OH)2 + 2CH3COOH → (CH3COO)2Ni + 2H2O
NiCO3 + 2CH3COOH → (CH3COO)2Ni + CO2 + 2H2O
On heating, the solution hydrolyzes depositing nickel hydroxide.

Chemical Properties

green monoclinic crystal(s); hygroscopic; used in textiles as a mordant [HAW93]


Nickel(II) acetate tetrahydrate can be used in synthesis of polynuclear-nickel polyoxotungstate cluster compounds that are ideal for the design of molecular magnets.

Safety Profile

Confirmed human carcinogen. Poison by ingestion and intraperitoneal routes. Mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes. See also NICKEL(II) ACETATE and NICKEL COMPOUNDS.

Purification Methods

The acetate crystallises from aqueous AcOH as the green tetrahydrate salt. It is soluble in 6 parts of H2O. It forms lower hydrates and should be kept in a well-sealed container. [Hardt & Pohlmann Z Anorg Allgem Chem 343 92 1966, Beilstein 2 IV 120.]
