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 ...
This template calculates the molecular mass (or molar mass) of a chemical compound. It is designed to be embedded in infoboxes {{ Infobox drug }} and {{ Chembox }} , but it can be used in-line just as well.
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Usually parameters reproduce the value, and the template adds the SI unit or additional standard text. While the topic is technical, we can strive to make the result readable text, and even verbose. For example, this is why the template writes "(at 0 °C)".
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
[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(II) chloride (or just nickel chloride) is the chemical compound NiCl 2. The anhydrous salt is yellow, but the more familiar hydrate NiCl 2 ·6H 2 O is green. Nickel(II) chloride, in various forms, is the most important source of nickel for chemical synthesis. The nickel chlorides are deliquescent, absorbing moisture from the air to form ...
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]
