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 ...
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.
Nickel trifluoroacetate tetrahydrate exists, as well as two emerald green acid trifluoroacetates, a bridged trinuclear form [Ni 3 (CF 3 COO) 6 (CF 3 COOH) 6](CF 3 COOH) and a hydrated acid form [Ni 3 (CF 3 COO) 6 (CF 3 COOH) 2 (H 2 O) 4](CF 3 COOH) 2 both with triclinic crystal form. The first has density 2.205 and the second 2.124.

A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+.The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table.
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]
