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 ...
Many salts of nickel(II) are isomorphous with salts of magnesium due to the ionic radii of the cations being almost the same. Nickel forms many coordination complexes. Nickel tetracarbonyl was the first pure metal carbonyl produced, and is unusual in its volatility. Metalloproteins containing nickel are found in biological systems. Nickel forms ...
Nickel(II) oxide is the chemical compound with the formula NiO. It is the principal oxide of nickel. [4] It is classified as a basic metal oxide. Several million kilograms are produced annually of varying quality, mainly as an intermediate in the production of nickel alloys. [5] The mineralogical form of NiO, bunsenite, is very rare.
nickel(II) carbonyl: 13463–39–3 Ni(C 2 H 3 O 2) 2: nickel(II) acetate: 373–02–4 NiCl 2: nickel(II) chloride: 7718–54–9 NiCl 2 •6H 2 O: nickel(II) chloride hexahydrate: 7791–20–0 NiCrO 4: nickel(II) chromate: 14721–18–7 NiF 2: nickel(II) fluoride: 10028–18–9 NiI 2: nickel(II) iodide: 13462–90–3 Ni(NO 3) 2: nickel(II ...
Neodymium nickelate can be prepared by dissolving neodymium(III) oxide and nickel(II) oxide in nitric acid, followed by heating the mixture in an oxygen atmosphere. [2] It can also be prepared by pyrolyzing a mixture of nickel nitrate and neodymium nitrate. [2] [3] It decomposes in high temperature (950 °C) by nitrogen: [2] 4 NdNiO 3 → 2 Nd ...
Nickel(II) fluoride is the chemical compound with the formula NiF 2. It is an ionic compound of nickel and fluorine and forms yellowish to green tetragonal crystals. Unlike many fluorides, NiF 2 is stable in air. Nickel(II) fluoride is also produced when nickel metal is exposed to fluorine.
Nickel(II) sulfate can crystallise with six water molecules yielding Retgersite or with seven making Morenosite which is isomorphic to Epsom salts. These contain the hexaquanickel(II) ion. [ 1 ] There is also an anhydrous form, a dihydrate and a tetrahydrate, the last two crystallised from sulfuric acid.
Nickel hydrazine nitrate (NHN), (chemical formula: [Ni(N 2 H 4) 3](NO 3) 2 is an energetic material having explosive properties in between that of primary explosive and a secondary explosive. [1] It is a salt of a coordination compound of nickel with a reaction equation of 3N 2 H 4 ·H 2 O + Ni(NO 3) 2 →〔Ni(N 2 H 4) 3 〕(NO 3) 2 ＋ 3H 2 O [2]
