Chemische Eigenschaften

Cadmium bromide is a white to yellowish crystalline powder.

Physikalische Eigenschaften

White to yellowish powder or flakes; hexagonal crystal system; hygroscopic; density 5.192g/cm3; melts at 568°C; vaporizes at 844°C; soluble in water, alcohol, ether, acetone, and liquid ammonia.

Verwenden

Made by heating cadmium to redness in bromine vapor. The yellowish crystalline powder is soluble in water and alcohol and is slightly soluble in ether. The crystals are deliquescent and must be kept in a well-stoppered bottle. Like its iodide counterpart, cadmium bromide was used in collodion in conjunction with an iodide of either ammonium or potassium.

synthetische

Cadmium bromide is prepared by heating cadmium with bromine vapor. Also the compound can be prepared by the treatment of dry cadmium acetate with glacial acetic acid and acetyl bromide. Alternatively, it may be obtained by dissolving cadmium or cadmium oxide in hydrobromic acid and evaporating the solution to dryness under helium in an inert atmosphere.

Allgemeine Beschreibung

Odorless white solid. Mixes with water.

Air & Water Reaktionen

Water soluble.

Reaktivit?t anzeigen

CADMIUM BROMIDE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.

Health Hazard

Inhalation causes coughing, sneezing, symptoms of lung damage. Ingestion produces severe toxic symptoms; both kidney and liver injuries may occur. Contact with eyes causes irritation.

Brandgefahr

Special Hazards of Combustion Products: Toxic cadmium oxide fumes may form in fires.

Sicherheitsprofil

Confirmed human carcinogen. When heated to decomposition it emits toxic fumes of Cd and Br-.

m?gliche Exposition

Cadmium bromide is used in photography, engraving, and lithography

l?uterung methode

Crystallise it from water (0.6mL/g) between 100o and 0o, and dry it at 110o. It forms the monohydrate below 36o and the tetrahydrate above 36o. [Wagenknecht & Juza in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1096 1965.]
