Definition and Usage Areas of Nickel chloride
Nickel chloride (or just nickel chloride) is the chemical component NiCl2. The anhydrous salt is yellow, but the more known hydrogen, NiCl2,6H2O, is green. Nickel(II) chloride, in various forms, is the most important source of nickel for chemical synthesis. Nickel chlorides absorb moisture from the air to form a solution. In case of prolonged inhalation exposure, nickel salts have been shown to be carcinogenic to the lungs and nasal passages.
The largest-scale production of NiCl2 includes the extraction of nickel matine with hydrochloric acid and residues from the refining of nickel-containing ores.
- Most NiCl2 is used for electroplating and nickel plating.
- During electroplating, the anode metal accelerates the dissolution of nickel, while acting to increase the electrode level.
- NiCl2 can be used as a catalyst for organic synthesis (eg, pyrazolophthalazinyl spiroxindoles) to synthesize nickel nanoparticles as a reductant and prepare nickel coordination compounds.
- It can also be used as an NH3 absorber in gas masks and a source of nickel ions for cell culture and toxicological studies.
- Nickel chloride solutions are used for electroplating nickel on other metal parts.
