Nickel(II) sulfate heptahydrate Usage And Synthesis

Chemical Properties

green to dark green needle-like crystals or powder

Uses

In electrolytic and electroless nickel-plating; as mordant in dyeing; in catalyst manufacture; in preparation of other nickel Compounds.

Uses

Nickel(II) sulfate hexahydrate may be used in the preparation of NiFe₂O₄ nanoparticles (NPs), required for the fabrication of a glucose biosensor.

Definition

ChEBI: A hydrate of nickel sulfate containing nickel (in +2 oxidation state), sulfate and water moieties in the ratio 1:1:7.

General Description

Nickel(II) sulfate hexahydrate is a hydrated nickel salt. Its thermal decomposition in the presence of air and helium has been studied. Its crystals exist in monoclinic and tetragonal polymorphic forms.
