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 .

Nickel ions can act as a cation in salts with many acids, including common oxoacids. Salts of the hexaaqua ion (Ni · 6 H 2 O 2+) are especially well known. Many double salts containing nickel with another cation are known. There are organic acid salts. Nickel can be part of a negatively charged ion (anion) making what is called a nickellate.
Nickel sulfide is any inorganic compound with the formula Ni x S y. These compounds range in color from bronze (Ni 3 S 2) to black (NiS 2). The nickel sulfide with simplest stoichiometry is NiS, also known as the mineral millerite. From the economic perspective, Ni 9 S 8, the mineral pentlandite, is the chief source of mined
As a mineral the ammonium nickel salt, (NH 4) 2 Ni(SO 4) 2 · 6 H 2 O, can be called nickelboussingaultite. [2] 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. [3]
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 ...
Nickelblödite is a rare nickel sulfate mineral with the formula Na 2 Ni(SO 4) 2 ·4H 2 O. [2] [4] Nickelblödite was discovered in nickel mines in Carr Boyd Rocks and Kambalda, Western Australia. [2] The mineral is a nickel-analogue of blödite, changoite, cobaltoblödite and manganoblödite - other representatives of the blödite group. [4]
Dichlorobis(ethylenediamine)nickel(II) is the inorganic compound with the formula NiCl 2 (en) 2, where en = ethylenediamine. The formula is deceptive: the compound is the chloride salt of the coordination complex [Ni 2 Cl 2 (en) 4] 2+. This blue solid is soluble in water and some polar organic solvents.
