General Description

Odorless yellow to brown solid. Sinks in water. (USCG, 1999)

Hazards

Reactivity Alerts

none

Air & Water Reactions

No rapid reaction with air. No rapid reaction with water.

Fire Hazard

Behavior in Fire: Decomposes to silver oxide, silver, and carbon dioxide; the reaction is not hazardous. (USCG, 1999)

Health Hazard

Contact with eyes causes irritation. If continued for a long period, ingestion or inhalation of silver compounds can cause permanent discoloration of the skin (argyria). (USCG, 1999)
