Nickel chloride Chemical Properties,Usage,Production

Description Nickel chloride is a brown or green colored solid. Most nickel chloride is used for electroplating and nickel plating, used to prepare various nickel salts and nickel catalysts; . During electroplating, it accelerates the dissolution of anode metal nickel, while acting to increase the electrolyte level of the solution. Nickel chloride can be used as catalyst for organic synthesis (e.g. pyrazolophthalazinyl spirooxindoles), to synthesize nickel nanoparticles as a reductant, and to prepare nickel coordination compounds, and and in industrial gas masks to protect from ammonia. It can also be used as an NH3 absorbent in gas masks and as a source of nickel ion for cell culture and toxicological studies.
Properties NICKEL CHLORIDE is a brown or green colored solid. Its hexahydrate is a green monoclinic crystal, which is weathered in dry air and deliquescent in moist air. It is easily soluble in water, ethanol and ammonia. It is easily reduced to nickel when heated in hydrogen and becomes nickel oxide by heating in the air. It loses water of crystallization and becomes anhydrous in high temperature. The aqueous solution is acidic. Nickel chloride can combine with the anions of many inorganic and organic molecules to form nickel complexes, and form insoluble precipitates in weak acids.
Preparation Anhydrous nickel chloride is prepared by burning nickel in chlorine gas.
Some other methods of preparation involve
(1) the action of acetyl chloride on nickel acetate in a nonaqueous solvent such as benzene:
(CH₃COO)₂Ni + 2CH₃COCl → NiCl₂ + 2CH₃COOCOCH₃
(2) the action of thionyl chloride on nickel chloride hexahydrate:
NiCl₂•6H₂O + 6SOCl₂ → NiCl₂ + 12HCl + 6SO₂
(3) heating nickel chloride hexahydrate or nickel chloride ammoniate:
NiCl2•6H₂O → NiCl₂ + 6H₂O
NiCl₂•6NH₃ → NiCl₂ + 6NH₃
The hexahydrate is prepared either by the action of hot dilute hydrochloric acid on nickel powder or by dissolving nickel oxide in dilute hydrochloric acid followed by crystallization. For the preparation of ammoniate, see Reactions below.
Reaction When ammonia gas is passed over anhydrous nickel chloride the product is an ammoniate, hexamine nickel chloride, NiCl2•6NH3. Ammoniate also can be prepared in solution by dissolving nickel chloride hexahydrate in an aqueous solution of ammonia.
Nickel chloride forms double salts with alkali metal chlorides or ammonium chloride. Such double salts, NH4Cl•NiCl2•6H2O, are obtained as hexahydrate when crystallized from a mixed solution of nickel chloride and ammonium chloride in equimolar amounts.
Warming a solution of nickel chloride and sodium hydroxide at moderate concentrations may partially precipitate a basic salt of indefinite composition. The average composition of this salt is NiCl2•3Ni(OH)2. Salt composition may vary depending on reaction conditions.
When hydrogen sulfide is passed through a buffered solution of nickel chloride, nickel sulfide, NiS, precipitates.
An alcoholic solution of nickel chloride, when treated with an ethereal solution of dithiobenzoic acid, C6H5CSSH, blue nickel(II) dithiobenzoate,(C6H5CSS)2Ni, is formed:
NiCl2 + 2C6H5CSSH→ Ni (C6H5CSS)2 + 2HCl
The product oxidizes readily to a violet dimeric nickel(IV) complex.
Health Hazards Acute Health Effects
The following acute (short-term) health effects may occur immediately or shortly after exposure to Nickel Chloride:
- Contact can irritate and bum the skin and eyes.
- Breathing Nickel Chloride can irritate the nose, throat and lungs causing cough, phlegm and shortness of breath.
Chronic Health Effects
The following chronic (long-term) health effects can occur at some time after exposure to Nickel Chloride and can last for months or years:

Cancer Hazard
- Nickel Chloride may cause mutations (genetic changes). Whether or not it poses a cancer or reproductive hazard needs further study.
Reproductive Hazard
- There is limited evidence that Nickel Chloride is a teratogen in animals. Until further testing has been done, it should be treated as a possible teratogen in humans.
Other Long-Term Effects
- Nickel Chloride may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash.
- Nickel Chloride may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, cough, and/or chest tightness.
- Repeated exposure may cause scarring of the lungs and may affect the kidneys.

Description Nickel chloride, NiCl2, is a water-soluble salt used in a variety of industries. It is typically produced and used either as an anhydrous salt or as a hydrate: nickel chloride hexahydrate as well as nickel chloride dihydrate. Nickel chloride is very rarely found in nature, and is produced via extraction from nickelcontaining ores via treatment with hydrochloric acid.
Chemical Properties Brown scales, deliquescent
Chemical Properties Nickel chloride appears as green or brown scales, or sparkling golden-yellow powder.
Physical properties The anhydrous salt forms yellow crystal scales; deliquesces; density 3.55 g/cm³; melts at 1,001°C; sublimes at 973°C; highly soluble in water, 64 g/100mL at 20°C; soluble in alcohol.
The hexahydrate forms green monoclinic crystals; deliquesces; extremely soluble in water, 254 g/100mL at 20°C, and about 600 g/100 ml at 100°C; also very soluble in alcohol.
Uses Nickel chloride is used for nickel plating cast zinc, as an agent in electrolytic refining of nickel, as a chemical intermediate for nickel catalysts and complex nickel salts, as an absorber of ammonia gas in industrial gas masks, as a catalyst in diarylamine and silicon tetrachloride production, as an agent in electrodeless plating of nickel, as an agent in tin–nickel alloy plating, and as a fungicide for control of rust and rustlike disease. However, workers exposed to different forms of nickel have an elevated risk of lung cancer. Besides, Ni and its compounds (particularly insoluble compounds of nickel) have been reported to be potent carcinogens and toxic agents in humans and experimental animals. Therefore, Ni compounds are considered to be an industrial/occupational health hazard.
Uses Nickel chloride (NiCl2) is used for electroplating nickel onto the surfaces of other metals and as a chemical reagent in laboratories.
Uses Nickel chloride solutions are used for electroplating nickel onto other metal items.It also is used to prepare various nickel salts and nickel catalysts; and in industrial gas masks to protect from ammonia.
Definition ChEBI: A compound of nickel and chloride in which the ratio of nickel (in the +2 oxidation state) to chloride is 1:2.
Nickel chloride is a yellow deliquescent solid with a boiling point of 973°C(1690°F). Nickel chloride is soluble in water and alcohol. Nickel chloride(hydrated),NiCI2·H20, is a gray deliquescent solid that is also soluble in water and alcohol.It is used in nickel plating.
Definition hexahydrate: A crystalline compoundthat has six moles of waterper mole of compound.
Production Methods Nickel chloride (hexahydrate) is obtained by reacting metal nickel powder or nickel oxide with hot, dilute hydrochloric acid.
Preparation Nickel(II) chloride can be obtained by reaction of the elements either in a flow system at high temperatures or by reaction in ethanol at 20°. It is readily prepared in the laboratory by dehydration of the hexahydrate with thionyl chloride.
General Description Nickel(II) chloride (NiCl₂) is a nickel based halide that is prepared by burning nickel in chlorine. It is a water soluble compound that crystallizes to form a hexahydrate. It is majorly utilized in organic synthesis as a catalyst and a precursor.
Hazard Confirmed carcinogen.
Flammability and Explosibility Non flammable
reaction suitability reagent type: catalyst
core: nickel
Safety Profile Confirmed human carcinogen. Poison by ingestion, intravenous, intramuscular, and intraperitoneal routes. An experimental teratogen. Experimental reproductive effects. Mutation data reported. When heated to decomposition it emits very toxic fumes of Cl-. See also NICICEL COMPOUNDS.
Potential Exposure Nickel chloride is used in electroplating and ink manufacturing.
Environmental Fate Nickel chloride is water soluble (642 g l^-1 for anhydrous; 2540 g l^-1 for hexahydrate) and would be expected to release divalent nickel into the water. Since nickel chloride quickly dissolves upon exposure to moist environments, and partially due to the ubiquity of nickel in soil, water, and air, tracking the course of the salt through the environment is difficult. This is particularly due to nickel’s ability to complex with anionic species other than chloride to form nickel oxide, sulfate, nitrate, carbonate, or acetate, among others.
Industrial uses of nickel chloride result in nickel being distributed mainly at soil surfaces and through surrounding waterways and water tables. Once distributed to the soil, nickel chloride produces nickel(II) ions to potentially form inorganic crystalline minerals or precipitates, can complex or adsorb onto organic and inorganic surfaces, can participate in cation exchange, and can exist as free-ion or chelated metal complexes in soil solution.
Shipping UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
Purification Methods It crystallises from dilute HCl to form the green hexahydrate. At 70o this dehydrates to the tetrahydrate, and at higher temperatures it forms the anhydrous salt. It sublimes in yellow hexagonal scales in a stream of HCl. Store it in a desiccator as it is deliquescent. [Hart & Partington J Chem Soc 104 1943.]
Toxicity evaluation The parent metal alters sodium balance and lipid metabolism; it induces metallothionein synthesis. Nickel chloride affects the T-cell portion of the immune system and suppresses the activity of natural killer cells. If given orally or by inhalation, nickel chloride has been reported to decrease iodine uptake by the thyroid gland. The lipid peroxidation properties of nickel can introduce potential malignancies in humans, as DNA strand gaps and breaks in DNA–protein cross-links can form. The downregulation of glycoprotein metabolism by nickel ions may produce nephrotoxicity in humans as well.
Incompatibilities Strong acids, potassium, sulfur. Forms an impact-sensitive mixture with potassium.
Toxics Screening Level The Initial Risk Screening Level (IRSL) for Nickel Chloride is 0.006 μg/m3 based on an annual averaging time.
Waste Disposal Recycle or disposal in a chemical waste landfill is recommended.
