Nickel(II) sulfate, or just nickel sulfate, usually refers to the inorganic compound with the formula NiSO 4 (H 2 O) 6. This highly soluble turquoise coloured salt is a common source of the Ni 2+ ion for electroplating .
When heated it dehydrates and then ends up producing nickel oxide and nickel sulfate. [5] Nickel thiosulfate NiS 2 O 3 has the same structure as the magnesium salt. It has alternating layers of octahedral shaped nickel 2+ hexahydrate, and tetrahedral shaped S 2 O 3 2− perpendicular to the β direction. [6] When heated to 90 °C it decomposes ...
[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]

Other double trichlorides include potassium nickel trichloride KNiCl 3 ·5H 2 O, [62] yellow cesium nickel trichloride CsNiCl 3, [62] lithium nickel trichloride LiNiCl 3 ·3H 2 O, [62] hyrdrazinium nickel tetrachloride, [62] and nickel ammonium chloride hexahydrate NH 4 NiCl 3 ·6H 2 O. [63] The tetrachloronickelates contain a tetrahedral NiCl ...

The Golden State Warriors lost their NBA Cup game against the Denver Nuggets 119-115 on Tuesday night, and head coach Steve Kerr was not happy with the way it ended.
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 ...
