Heating nickel sulfate dehydrates it, and then 700° it loses sulfur trioxide, sulfur dioxide and oxygen. ... 2 a = 4.98, c = 26.59, and V = 571, formula weight Z=3 ...
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 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
Nickel(II) sulfate is produced in large amounts by dissolving nickel metal or oxides in sulfuric acid, forming both a hexa- and heptahydrate [46] useful for electroplating nickel. Common salts of nickel, such as chloride, nitrate, and sulfate, dissolve in water to give green solutions of the metal aquo complex [Ni(H 2 O) 6 ] 2+ .
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 ...
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]
Nickel (III) oxide is the inorganic compound with the formula Ni 2 O 3. It is not well characterized, [1] and is sometimes referred to as black nickel oxide. Traces of Ni 2 O 3 on nickel surfaces have been mentioned. [2] [3] Nickel (III) oxide has been studied theoretically since the early 1930s, [4] supporting
A nickelate is an anion containing nickel or a salt containing a nickelate anion, or a double compound containing nickel bound to oxygen and other elements. Nickel can be in different or even mixed oxidation states, ranging from +1, +2, +3 to +4. The anions can contain a single nickel ion, or multiple to form a cluster ion.
