Nickel nitrate is the inorganic compound Ni(NO 3) 2 or any hydrate thereof. In the hexahydrate, the nitrate anions are not bonded to nickel. Other hydrates have also been reported: Ni(NO 3) 2. 9H 2 O, Ni(NO 3) 2. 4H 2 O, and Ni(NO 3) 2. 2H 2 O. [3] It is prepared by the reaction of nickel oxide with nitric acid: NiO + 2 HNO 3 + 5 H 2 O → Ni ...
The heptahydrate crystallises from water below 31.5 above this blue hexhydrate forms, and above 53.3 the green form. [20] Heating nickel sulfate dehydrates it, and then 700° it loses sulfur trioxide, sulfur dioxide and oxygen. Other important nickel compounds in this class are nickel carbonate, nickel nitrate, and nickel phosphate

Nickel(II) sulfate is produced in large amounts by dissolving nickel metal or oxides in sulfuric acid, forming both a hexa- and heptahydrate [46] useful for electroplating nickel. Common salts of nickel, such as chloride, nitrate, and sulfate, dissolve in water to give green solutions of the metal aquo complex [Ni(H 2 O) 6 ] 2+ .
Nickel acetate exists as an intermediate and the final result is that solid nickel, nickel oxide, Ni 3 C and carbon remain. [9] With malonate nickel can form a bis-malonato-nickelate anion, which can form double salts. [10] Nickel maleate can be made from maleic acid and nickel carbonate in boiling water.
Consider the case of nickel(II) chloride hexahydrate. This species has the formula NiCl 2 (H 2 O) 6 . Crystallographic analysis reveals that the solid consists of [ trans - NiCl 2 (H 2 O) 4 ] subunits that are hydrogen bonded to each other as well as two additional molecules of H 2 O .
