General Description

Odorless white to gray solid. Sinks and mixes with water. (USCG, 1999)

Hazards

Reactivity Alerts

none

Air & Water Reactions

Water soluble.

Fire Hazard

No information available.

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)

Reactivity Profile

SILVER SULFATE 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)

Metals, Less Reactive
