Is NiS solid or aqueous?
Nickel sulfide is an inorganic compound with the formula NiS. It is a black solid that is produced by treating nickel(II) salts with hydrogen sulfide. Many nickel sulfides are known, including the mineral millerite, which also has the formula NiS.
Is Ni2S3 soluble in water?
Nickel Sulfide is a moderately water and acid soluble Nickel source for uses compatible with sulfates.
Is nickel sulfide toxic?
Unusual Fire and Explosion Hazards: When heated to decomposition, nickel sulfide may emit toxic fumes of oxides of sulfur. Effects of Exposure: Nickel is a confirmed carcinogen with experimental carcinogenic, neoplastigenic, tumorigenic and teratogenic data.
What is nickel sulfide used for?
Nickel sulphide and laterite ore is used to make nickel metal, predominantly for the production of stainless steel as well as nickel sulphate, a key ingredient in the batteries that drive electric vehicles. More than two thirds of global nickel production is used to produce stainless steel.
Is nickel sulphide magnetic?
From the results of measurements of the susceptibility, specific heat and other data, it was found that nickel sulfide is antiferromagnetic with the Néel point at 150°K. However, below 120°K, the susceptibility of the powder specimen increased with the fall of temperature and also showed a dependence of magnetic field.
Is nickel sulfate soluble?

Is nickel flammable?
Nickel powder and Raney Nickel are FLAMMABLE SOLIDS.
Is nickel magnetic?
Nickel. Nickel is also a popular magnetic metal with ferromagnetic properties. Its compounds are also found in the earth’s core. Nickel has historically been used to make coins.
What is the normal size of a nickel sulfide?
A range of concentrations (from 5-50 mM) was also investigated at 180 °C and while in all cases pure α-NiS was formed, particle sizes varied significantly. Thus at low concentrations average particle sizes were ca. 100 nm, but at higher concentrations they increased to ca. 150 nm.
