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 ...
Nickel(II) nitrite is an inorganic compound with the chemical formula Ni(NO 2) 2. [1] Anhydrous nickel nitrite was first discovered in 1961 by Cyril Clifford Addison, who allowed gaseous nickel tetracarbonyl to react with dinitrogen tetroxide, yielding a green smoke. Nickel nitrite was the second transition element anhydrous nitrite discovered ...
By reacting nickel with chalcogens, nickel sulfide, nickel selenide, and nickel telluride are formed. There are numerous sulfides: Ni 1.5 S, Ni 17 S 18 , Ni 3 S 2 ( heazlewoodite ), Ni 3 S 4 ( polydymite ), Ni 9 S 8 ( godlevskite ), NiS ( millerite ) and two other NiS forms, NiS 2 ( vaesite ) in pyrite structure.
Nickel sulfamate can be used for nickel or mixed nickel-tungsten plating. [8] It can be formed by the action of sulfamic acid on nickel carbonate. [9] Nickel selenite NiSeO 3 has many different hydrates, anhydrous NiSeO 3 · 1 ⁄ 3 H 2 O, NiSeO 3 · H 2 O, NiSeO 3 · 2 H 2 O (which is also a mineral called ahlfeldite), and NiSeO 3 · 4 H 2 O. [10]
