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.
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 ...
Contact smart cards (with chip) have a contact zone consisting of a few small contact petals. When the card is inserted into the reader, the chip connects with the card reader which can then read and write information. The standard ISO/IEC 7816 also regulates data exchange protocols and some aspects of work with other smart card data. [1] [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.
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]
There are different designations for differently prepared Urushibara nickel catalysts. [4] The most common is U-Ni-A and U-Ni-B. U-Ni-A is prepared by digesting the precipitated nickel with an acid such as acetic acid. U-Ni-B is prepared by digesting with a base such as sodium hydroxide. After the digestion with acid most of the zinc and zinc ...
The geometry of the nickel(II) ion is square planar. [2] It is surrounded by two equivalents of the conjugate base (dmgH −) of dimethylglyoxime (dmgH 2).The pair of organic ligands are joined through hydrogen bonds to give a macrocyclic ligand.
