| Questions And Answer | Back Directory | [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.
| [Uses]
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.
| [Preparation]
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.

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