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).
Contents
Properties
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 are mildly toxic and are carcinogenic. All are denser than water.
Availability
Nickel(II) sulfate is sold in many chemical suppliers.
Preparation
Nickel sulfate can be made by reacting nickel hydroxide with sulfuric acid.
Projects
- Growing crystals
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
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.
