Nickel nitrate is the chemical 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. The nitrate anions are not bonded to nickel.
[Ni(H2O)6](NO3)2 is highly soluble in water, giving emerald green solutions. It is a useful precursor to other nickel(II) derivatives where the water ligands would be replaced.
Like other nitrates, nickel nitrate is oxidizing, so that caution should be exercised when it contacts with reducing materials such as organic substances. It is also irritating to the eyes, skin and, upon inhalation of the dust, respiratory tract. It may cause skin allergy. Nickel nitrate is a carcinogen, along with most other nickel compounds. The nickel ion is also toxic to aquatic organisms.

Nickel(II) nitrate, also known as nickelous nitrate, is a chemical compound. Its chemical formula is Ni(NO3)2. It contains nickel in its +2 oxidation state. It also contains nitrate ions.
Contents |
Nickel(II) nitrate is a green crystalline solid. It dissolves in water. Because it has nitrate ions, it is an oxidizing agent. It normally has water molecules attached to it, making it hydrated.
It is made by dissolving nickel metal in nitric acid.
It is used as a source of nickel(II), but nickel(II) chloride and nickel(II) sulfate are used more commonly.
It is an oxidizing agent, so it should be kept away from things that can burn. It also is toxic to things that live in the water. It is a carcinogen.
