Nickel chloride Chemical Properties,Uses,Production


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.


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.


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:
(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.


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.

Chemical Properties

Brown scales, deliquescent

Chemical Properties

Nickel chloride appears as green or brown scales, or sparkling golden-yellow powder.


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.


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.


Confirmed carcinogen.

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.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.


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.]


Strong acids, potassium, sulfur. Forms an impact-sensitive mixture with potassium.

Waste Disposal

Recycle or disposal in a chemical waste landfill is recommended.
