NICKEL AMMONIUM SULFATE Usage And Synthesis

Chemical Properties

dark green crystals

Chemical Properties

Nickel ammonium sulfate is a green, odorless powder.

Uses

Nickel electrolyte for electroplating.

Definition

ChEBI: A nickel coordination entity comprising ammonium, nickel and sulfate in which the ratio of ammonium to iron(2+) to sulfate ions is 2:1:2.

General Description

NICKEL AMMONIUM SULFATE is a green crystalline solid. Mildly toxic, carcinogenic. When heated to decomposition NICKEL AMMONIUM SULFATE emits highly toxic fumes of metallic nickel, oxides of sulfur, and oxides of nitrogen (Lewis, 3rd ed., 1993, p. 910). The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. NICKEL AMMONIUM SULFATE is used for electroplating nickel.

Air & Water Reactions

Water soluble. Forms an acidic aqueous solution.

Reactivity Profile

NICKEL AMMONIUM SULFATE is a "double salt" that is a weak oxidizing agent. Gives an acidic solution when dissolved in water.

Hazard

See nickel

Health Hazard

Inhalation causes irritation of nose and throat. Ingestion causes vomiting. Contact with eyes causes irritation. Contact with skin may cause dermatitis.

Fire Hazard

Special Hazards of Combustion Products: Toxic oxides of nitrogen may be formed in fire.

Safety Profile

Confirmed human carcinogen. Poison by ingestion. When heated to decomposition it emits toxic fumes of NOx, SOx, and Ni.

Potential Exposure

This material is used in electroplating.

Shipping

UN3288 Toxic solids, inorganic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard Class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

Purification Methods

Crystallise this salt from water (3mL/g) on cooling from 90o to 0o.

Incompatibilities

Forms an acidic solution with water. A weak oxidizer; keep away from combustible materials, reducing agents, including hydrides. Possible violent reaction with strong acids. Incompatible with nickel nitrate, sulfur, selenium, wood, organics, and other combustibles.
