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 ...
International Chemical Safety Cards (ICSC) are data sheets intended to provide essential safety and health information on chemicals in a clear and concise way.The primary aim of the Cards is to promote the safe use of chemicals in the workplace and the main target users are therefore workers and those responsible for occupational safety and health.
Materials that may form explosive mixtures with water and are capable of detonation or explosive reaction in the presence of a strong initiating source. Materials may polymerize, decompose, self-react, or undergo other chemical change at normal temperature and pressure with moderate risk of explosion (e.g., ammonium nitrate). 2.
[Ni(NH 3) 6] 2+, like all octahedral nickel(II) complexes, is paramagnetic with two unpaired electrons localized on each Ni center. [Ni(NH 3) 6]Cl 2 is prepared by treating aqueous nickel(II) chloride with ammonia. It is useful as a molecular source of anhydrous nickel(II). [2]
Nickel terephthalate can be made by a double decomposition of sodium terephthalate and nickel nitrate. Nickel terephthalate precipitates. Its solubility is 0.38 g/100g water at 25 °C. In ammonium hydroxide a violet solution forms. Boiling acetic acid converts the nickel to nickel acetate.
The nickel holding is done by a "nickel binding hook" which as the amino acid pattern H 2 N-His-Cys-X-X-Pro-Cys-Gly-X-Tyr-rest of protein, where the bold bits are ligands for the nickel atom. [ 57 ] Nickel transporter proteins exist to move nickel atoms in the cell. in E. coli these are termed Nik A, Nik B, Nik C, Nik D, Nik E.
Bis(2,4-pentanedionato)nickel(II) is prepared by treating nickel nitrate with acetylacetone in the presence of base. The product is the blue-green diaquo complex Ni(CH 3 COCHCOCH 3) 2 (H 2 O) 2. [9] Ni(NO 3) 2 + 2 CH 3 COCH 2 COCH 3 + 2 H 2 O + 2 NaOH → Ni(CH 3 COCHCOCH 3) 2 (H 2 O) 2 + 2 NaNO 3
Nickel nitrate commonly crystallises with six water molecules, [1] but can also be anhydrous, or with two, four or nine waters. [11] triphenylphosphine oxide nickel nitrate [(C 6 H 6) 3 PO] 2 Ni(NO 3) 2 is non ionic, with nitrato as a ligand. It can be made from nickel perchlorate. It is yellow and melts at 266 °C. [12]
