NICKEL(II) HYDROXIDE Chemical Properties,Uses,Production

Physical Properties

Green hexagonal crystal; density 4.10 g/cm3; decomposes to NiO on heating at 230°C; insoluble in water; KSP 5.47x10-16; monohydrate is insoluble in water but soluble in dilute acids and ammonia.

Preparation

Nickel hydroxide is prepared by various methods, mostly involving reaction of caustic soda or caustic potash with a soluble nickel salt. Thus, treating nickel sulfate solution with sodium hydroxide forms a voluminous green gel. The gel crystallizes on prolonged storage. Alternatively, the solution on neutralization forms a fine precipitate of nickel hydroxide. Nickel nitrate also is used as starting material to prepare nickel hydroxide. Its aqueous solution, on treatment with sodium or potassium hydroxide, yields a gelatinous precipitate of nickel hydroxide which may be extracted with hot alcohol to form high purity product.
Nickel hydroxide in high purity is prepared by an electrolytic process using metallic nickel as the anode and nickel nitrate solution as the electrolyte. Nickel hydroxide is electrodeposited at an inert cathode.

Chemical Properties

Black powder.

Chemical Properties

Nickel hydroxide is a light, apple-green powder.

Uses

Due to its redox behavior, it finds use in rechargeable battery electrodes. It is useful for the storage of electrochemical energy, with potential applications in car batteries. It is a potential material for several biological applications, for example in chromosomal DNA quantification assay.

Uses

Nickel salts.

Uses

Nickel hydroxide was used as a reference material in a study where the influence of stacking faults on the electrochemical activity of Ni(OH)2 electrodes was studied.

Preparation

This is precipitated as finely divided green powder when an alkali metal hydroxide solution is added to an aqueous solution of a nickel(II) salt. It is frequently difficult to filter at first but becomes more crystalline upon prolonged standing. If the nickel salt is incompletely precipitated, especially if very strong solutions of nickel(II) are used, then the precipitate may be a basic salt. This is particularly true of the halides, in which case compounds such as NiCl2?3Ni(OH)2 and NiCl2?Ni(OH)2 have been characterized.

Production Methods

Nickel hydroxide is obtained either by treating nickel sulfate solution with sodium hydroxide or by hot alcohol extraction of the precipitate formed as a result of the reaction of nickel nitrate with potassium hydroxide. Nickel hydroxide is used for the manufacture of nickel–cadmium electric cells, and as an intermediate product during the manufacture of nickel catalysts.

Hazard

Confirmed carcinogen.

Safety Profile

Confirmed carcinogen with experimental carcinogenic and tumorigenic data. Poison by subcutaneous route. See also NICKEL COMPOUNDS.

Potential Exposure

It may be found in the workplace as a dust, liquid, or acid solution. This compound may be used in nickel plating operations.

Shipping

UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard Class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

Incompatibilities

Incompatible with strong acids. Aqueous solution may be acidic.

Waste Disposal

Recover and recycle where possible or dispose of in a chemical waste landfill.
