The anhydrous nickel nitrate is typically not prepared by heating the hydrates. Rather it is generated by the reaction of hydrates with dinitrogen pentoxide or of nickel carbonyl with dinitrogen tetroxide: [3] Ni(CO) 4 + 2 N 2 O 4 → Ni(NO 3) 2 + 2 NO + 4 CO. The hydrated nitrate is often used as a precursor to supported nickel catalysts. [3]
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) 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 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]
Nickel(II) hydroxide Ni(OH) 2, the main hydroxide of nickel is coloured apple green. It is known as the mineral theophrastite. β-NiO(OH) is a black powder with nickel in the +3 oxidation state. It can be made by oxidising nickel nitrate in a cold alkaline solution with bromine.
The federal Hazardous Products Act and associated Controlled Products Regulations, administered by the Workplace Hazardous Materials Bureau residing in the federal Department of Health Canada, [citation needed] established the national standard for chemical classification and hazard communication in Canada and is the foundation for the workers' "right-to-know" legislation enacted in each of ...
Nickel electroplating was developed in the first half of the 19th century, with notable experiments made by Golding Bird (1837) and nickel nitrate patent by Joseph Shore (1840). The first practical recipe, an aqueous solution of nickel and ammonium sulfates, was invented by Böttger in 1843 and was in use for 70 years. [8]
Cobalt nitrate is the inorganic compound with the formula Co(NO 3) 2. xH 2 O. It is cobalt (II)'s salt . The most common form is the hexahydrate Co(NO 3 ) 2 ·6H 2 O, which is a red-brown deliquescent salt that is soluble in water and other polar solvents.
