Nickel nitrate is the inorganic compound Ni(NO3)2 or any hydrate thereof.
The anhydrous form is not commonly encountered, thus "nickel nitrate" usually refers to nickel(II) nitrate hexahydrate.
The formula for this species is written in two ways: Ni(NO3)2.6H2O and, more descriptively [Ni(H2O)6](NO3)2.
The latter formula indicates that the nickel(II) center is surrounded by six water molecules in this hydrated salt.
In the hexahydrate, the Nickel nitrate are not bonded to nickel.
Also known are three other hydrates: Ni(NO3)2.9H2O, Ni(NO3)2.4H2O, and Ni(NO3)2.2H2O. Anhydrous Ni(NO3)2 is also known.
Nickel Nitrate is a highly water soluble crystalline Nickel source for uses compatible with nitrates and lower (acidic) pH.
All metallic nitrates are inorganic salts of a given metal cation and the nitrate anion.
Nickel nitrate is a univalent (-1 charge) polyatomic ion composed of a single nitrogen atom ionically bound to three oxygen atoms (Formula: NO3) for a total formula weight of 62.05. Nitrate compounds are generally soluble in water.
Nickel nitrates are also oxidizing agents.
When mixed with hydrocarbons, Nickel nitrates can form a flammable mixture.
Nickel nitrates are excellent precursors for production of ultra high purity compounds and certain catalyst and nanoscale (nanoparticles and nanopowders) materials.
Nickel Nitrate is generally immediately available in most volumes.
High purity, submicron and nanopowder forms may be considered.
Nickel nitrate is a green crystalline solid.
Nickel nitrate is soluble in water.
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 this material.
Nickel nitrate is used in nickel plating and to make nickel catalysts for use in chemical manufacture.

PREPARATION OF NICKEL NITRATE:
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.

HANDLING AND STORAGE OF NICKEL NITRATE:
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage and moisture. Isolate from any source of heat or ignition.
Avoid storage on wood floors.
Separate from in compatibles, combustibles, organic or other readily oxidizable materials.
Areas in which exposure to nickel metal or soluble nickel compounds may occur should be identified by signs or appropriate means, and access to the area should be limited to authorized persons.
Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
