| Uses | Nickel nitrate is used in the preparation of nickel-impregnated catalysts. It also is used to make nickel plates in nickel-cadmium batteries. Other applications are in ceramics to produce brown colors and in preparing nickel oxide.
|
| Preparation | Nickel nitrate hexahydrate may be prepared by several methods based on the reaction of dilute nitric acid on nickel powder, nickel oxide or nickel carbonate. The reaction is exothermic and requires controlled cooling during production. The hexahydrate can be dehydrated to anhydrous salt by treatment with fuming nitric acid.
|
| Chemical Properties | Green, deliquescent crystals.Soluble in water, ammonium
hydroxide, and alcohol. |
| Chemical Properties | Nickel nitrate is a green powder. |
| Physical properties | The hexahydrate forms emerald green monoclinic crystals; hygroscopic; density 2.05 g/cm3; isomorphous with corresponding cobalt salt; melts at 56.7°C; loses water on heating, decomposing to nickel oxide; very soluble in water; aqueous solution acidic; soluble in ethanol. |
| Uses | Nickel plating, preparation of nickel catalysts,
manufacture of brown ceramic colors. |
| General Description | NICKEL NITRATE is a green crystalline solid. NICKEL NITRATE is soluble in water. NICKEL NITRATE is noncombustible, but NICKEL NITRATE will accelerate the burning of combustible materials. If large quantities are involved in a fire or the combustible material is finely divided, an explosion may result. Prolonged exposure to fire or heat may result in an explosion. Toxic oxides of nitrogen are produced in fires involving NICKEL NITRATE. NICKEL NITRATE is used in nickel plating and to make nickel catalysts for use in chemical manufacture. |
| Air & Water Reactions | Nickel nitrate, Ni(N03)2·SH20, is green, monoclinic, deliquescent crystals that are soluble in water and alcohol; a dangerous fife hazard and strong oxidant that is used in nickel plating and the preparation of catalysts and brown ceramic coloring. |
| Reactivity Profile | Green, crystalline material, toxic and carcinogenic. A powerful oxidizer, NICKEL NITRATE may cause a violent reaction with reducing materials (e.g., magnesium or aluminum powder, tin(II) chloride). Dangerous fire hazard, acts as oxygen carrier. When heated to decomposition NICKEL NITRATE emits highly toxic fumes of oxides of nitrogen [Lewis, 3rd ed., 1993, p. 915]. Complexes with tetrammine and tetrahydrazine are explosive [Bretherick, 5th ed., 1995, p. 1685]. |
| Hazard | Dangerous fire risk, strong oxidizing agent. |
| Health Hazard | Inhalation of dust causes irritation of nose and throat. Ingestion causes vomiting. Dust irritates eyes and may cause dermatitis in contact with skin. |
| Flammability and Explosibility | Non flammable |
| Safety Profile | Confirmed human
carcinogen. Poison by intravenous route.
Experimental reproductive effects. Mutation
data reported. A powerful oxilzer. When
heated to decomposition it emits very toxic
fumes of NOx. See also NICKEL
COMPOUNDS and NITRATES. |
| Potential Exposure | Nickel nitrate is used in electroplating,
in nickel catalyst production for making other chemicals
and the manufacture of brown ceramic colors. |
| Shipping | UN2725 Nickel Nitrate, Hazard Class: 5.1;
Labels: 5.1-Oxidizer. |
| Incompatibilities | A strong oxidizer. Incompatible with
strong acids; sulfur, combustibles, organics, and other easily
oxidizable materials. Noncombustible, but it will accelerate
the burning of combustible materials. If large
quantities are involved in a fire or the combustible material
is finely divided, an explosion may result. Prolonged exposure
to fire or heat may result in an explosion. |
| Waste Disposal | Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations
governing storage, transportation, treatment, and waste
disposal. |
