Nickel(II) sulfate is inorganic salt of nickel with formula NiSO4. Nickel sulfate has many forms, anhydride, hexahydrate and heptahydrate. In nature occurs as rare mineral retgersite (hexahydrate) or morenosite (heptahydrate).

Properties

Chemical

Addition of ammonium sulfate to concentrated aqueous solutions of nickel sulfate precipitates Ni(NH4)2(SO4)2·6H2O. This blue-coloured solid is analogous to Mohr's salt, Fe(NH4)2(SO4)2·6H2O.

Physical

Nickel sulfate is a yellow, green or blue colored, crystalline inorganic compound that produces toxic gases upon heating. Nickel sulfate is used in electroplating and as a chemical intermediate to produce other nickel compounds.

Anhydrous nickel sulfate is a yellow-green crystalline solid. Nickel sulfate can also be obtained as a hexahydrate which is blue to emerald green, and as a heptahydrate (NiSO4·7H2O), which is green. Samples can contain variable quantities of water, depending on their previous exposure to moisture or conditions. All forms of nickel sulfate, anhydrous or hydrated are mildly toxic and are carcinogenic. All forms of nickel sulfate, anhydrous or hydrated are paramagnetic.

Availability

Nickel(II) sulfate is sold by many chemical suppliers.

Preparation

Nickel sulfate can be made by reacting nickel hydroxide or nickel oxide powder with sulfuric acid. The product is purified by recrystallization from concentrated solution.

Projects

  • Growing crystals
  • Nickel plating
  • Make nickel carbonate
  • Make nickel coordination complexes

Handling

Safety

Exposure to this substance can cause severe dermatitis, skin and asthma-like allergies and affects the lungs, kidneys, gastrointestinal tract and neurological system. Nickel sulfate is a known carcinogen and is associated with an increased risk of developing lung and nasal cancers.

Storage

Nickel(II) sulfate is best stored in closed bottles.

Disposal

Nickel(II) sulfate should be reduced to an insoluble form and taken to disposal centers. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment.
