Nickel (II) acetate (Ni (CH3 COO)2 ) 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 or nickel (II) carbonate with acetic acid.
Ni + 2 CH3 COOH → C4 H6 NiO4 + H2
NiCO3 + 2 CH3 COOH → C4 H6 NiO4 + CO2 + H2 O
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.
??? ??
Green, monoclinic crystals; effloresces somewhat in air.Soluble in water and alcohol.??? ??
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.??
Textiles (mordant), catalyst.?? ??
Dull green odorless solid. Sinks and mixes slowly with water.??? ?? ??
Water soluble.?? ???
Nickelous acetate is a green, crystalline material, mildly toxic and carcinogenic. Combustible when exposed to heat or flame. When heated to decomposition Nickelous acetate emits acrid smoke and irritating fumes [Lewis, 3rd ed., 1993, p. 909].???
Toxic by ingestion, a carcinogen (OSHA).????
Inhalation causes irritation of nose and throat. Ingestion causes vomiting. Contact with eyes causes irritation. May cause dermatitis in contact with skin.Safety Profile
Confirmed carcinogen with experimental neoplastigenic and tumorigenic data. Poison by ingestion, intraperitoneal, and subcutaneous routes. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits irritating fumes. See also NICKEL COMPOUNDS.Safety
Nickel salts are carcinogenic and irritate the skin.???? ?? ?? ?? ? ???
