General Description

White powder or crystal. Turns green to dark blue on exposure to sunlight. Sinks and mixes slowly with water. (USCG, 1999)

Hazards

Reactivity Alerts

none

Air & Water Reactions

Mixes slowly with water.

Fire Hazard

No information available.

Health Hazard

INHALATION: Irritation of upper respiratory tract. EYES: Irritation of conjunctivae. SKIN: Irritation, acne-like rash (usually from prolonged exposure). INGESTION: Vomiting caused by local irritant and astringent action of ionic Cu on stomach and intestines. Pain in mouth, esophagus, and stomach. Inorganic bromides produce depression, psychoses, and mental deterioration. (USCG, 1999)

Reactivity Profile

COPPER (I) 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.

Belongs to the Following Reactive Group(s)
