GOLD CHLORIDE (Brown) (HAuCl4.3H2O)
SYNONYMS
Auric chloride, chloroauric (III) acid, trihydrate.
CHARACTERISTICS
Brown, hygroscopic lumps or crystals.
INCOMPATIBILITY
Heating will produce toxic fumes of chlorine compounds. Gold
chloride is generally stable but it can react with alkalis.
HEALTH HAZARD DATA
A corrosive substance and an eye irritant and may irritate the
skin. It is regarded as being of low toxicity by inhalation or
ingestion.
HANDLING and GENERAL PRECAUTIONS
Avoid eye contact.
