Nickel sulfate is an inorganic compound that exists in different states depending on its hydrated forms. The chemical formula for nickel sulphate is NiSO4. Based on the degree of hydration the colour of the compound differs. Nickel dust is highly flammable. The salts of nickel compounds are toxic in nature and nickel sulphate is a known carcinogen. It is yellow and readily soluble in water.

Uses of Nickel Sulfate – NiSO4

The main use of nickel sulfate is as the electrolyte for the metal-finishing application of nickel electroplating.

Used as a mordant, in colouring metals, in ceramics and for producing driers for use in protective shields.

A special nickel-iron alloy is widely used in lead frames, while a Cu-Ni-Sn alloy is used in terminals, clips and springs.

Nickel sulfate is used in electroplating baths and for the production of other nickel compounds for example nickel hydroxide.
