Nickel carbonate
Green crystals that melting at 56c (decomposes); soluble in acid, insoluble in water; used in electroplating, as a catalyst production for organic chemical manufacture, petroleum refining and edible oil hardening.
From the industrial perspective, the most important nickel carbonate is basic nickel carbonate with the formula ni4co3(oh)6(h2o)4. Simpler carbonates, ones more likely encountered in the laboratory, are nico3 and its hexahydrate. All are paramagnetic green solid containing ni2+ cations. The basic carbonate is an intermediate in the hydrometallurgical purification of nickel from its ores and is used in electroplating of nickel.
Nickel(ii) formate dihydrate is one of numerous organometallic compounds .
Organometallics are useful reagent, catalyst, and precursor materials with applications in thin film deposition, industrial chemistry, pharmaceuticals, led manufacturing, and others
Nickel Acetate
Efflorescent green crystals; decompose on heating; soluble in water and alcohol;
used in plating processes,anodize coatings and as textile dyeing mordant.
Nickel(ii) fluoride is the chemical compound with the formula nif2. Unlike many fluorides, nif2 is stable in air.
Nif2 comprises the passivating surface that forms on nickel alloys, e.G. Monel, which is why such materials are good to store or transport hydrogen fluoride or elemental fluorine.
Nickel is one of the few materials that can be used to store fluorine because it forms this coating.
It is also used as a catalyst for the synthesis of chlorine pentafluoride.
Fluoride compounds have diverse applications in current technologies and science, from oil refining and etching to syntheticorganic chemistry and the manufacture of pharmaceuticals.
