Nickel Nitrate By Hemal Impex

We are the loyalist in manufacturing, exporting, distributing and supplying an extensive assortment of Nickel Nitrate in Ankleshwar, Gujarat, India. It 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 nitrate anions 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[2]. It is prepared by the reaction of nickel oxide with nitric acid:

>> NiO + 2 HNO3 + 5 H2O Ni(NO3)2.6H2O.
