silver picrate Usage And Synthesis
Chemical Properties
Silver picrate is a yellow powder or crystalline material which turns brown when heated or exposed to light. Commercial product is a white to light tan solid paste. Contains about 35% water, which reduces its tendency toward rapid decomposition or explosion. Considered safe for storage, handling and shipping, but should be treated as an explosive.
Chemical Properties
Yellow crystals containing 30% silver, soluble in water. Slightly soluble in alcohol and acetone; insoluble in ether and chloroform.
Uses
Medicine (antimicrobial agent).
General Description
A white to light colored solid paste. Contains about 35% water, which reduces its tendency toward rapid decomposition or explosion. Considered safe for storage, handling and shipping, but should be treated as an explosive. Contact may cause irritation to skin, eyes, and mucous membranes. May be toxic by ingestion.
Air & Water Reactions
Water soluble [Hawley].
Reactivity Profile
silver picrate may be ignited by heat, sparks or flames. The DRIED OUT material may explode if exposed to heat, flame, friction or shock.
Hazard
Severe explosion risk. Very toxic.
Health Hazard
Some are toxic and may be fatal if inhaled, swallowed or absorbed through skin. Contact may cause burns to skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
Safety Profile
A flammable solid and unstable substance forbidden from transport. When heated to decomposition it emits toxic vapors of NOx.
Potential Exposure
Used in antibacterial medicines.
Shipping
UN1347 Silver picrate, wetted with not ,30 % water, by mass, Hazard Class: 4.1; Labels: 4.1-Flammable solid.
Incompatibilities
Organics or other oxidizable materials. Dried out material is unstable and a severe explosion risk; protect from shock, light, and vibration.
