| | Nickel(II) acetate tetrahydrate Usage And Synthesis |
| 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.
| | Chemical Properties | green monoclinic crystal(s); hygroscopic; used in textiles as a mordant [HAW93] | | Uses | Nickel(II) acetate tetrahydrate can be used in synthesis of polynuclear-nickel polyoxotungstate cluster compounds that are ideal for the design of molecular magnets.
| | Uses | Nickel(II) Acetate Tetrahydrate is a reactant in the synthesis of metalloprophyrazines as active components of membranes of anion-selective electrodes. | | 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.] |
