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 .

Tutton's salts are a family of salts with the formula M 2 M'(SO 4) 2 (H 2 O) 6 (sulfates) or M 2 M'(SeO 4) 2 (H 2 O) 6 (selenates). These materials are double salts, which means that they contain two different cations, M + and M' 2+ crystallized in the same regular ionic lattice. [1]

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.
As a mineral the ammonium nickel salt, (NH 4) 2 Ni(SO 4) 2 · 6 H 2 O, can be called nickelboussingaultite. [38] With sodium, the double sulfate is nickelblödite Na 2 Ni(SO 4) 2 · 4 H 2 O from the blödite family. Nickel can be substituted by other divalent metals of similar sized to make mixtures that crystallise in the same form. [39]
The mixture of nickel carbonyl and syngas is heated to 220–250 °C, resulting in decomposition back to nickel and carbon monoxide: Ni(CO) 4 (g) → Ni(s) + 4 CO(g) Steps 2 and 3 illustrate a chemical transport reaction , exploiting the properties that (1) carbon monoxide and nickel readily combine to give a volatile complex and (2) this ...
