Silver acetate is a silver compound with the formula CH3COOAg.

Properties

Chemical

Silver acetate decomposes when heated to give carbon dioxide, water and silver metal.

CH3COOAg → Ag + CO2 + H2O

Physical

Silver acetate is a white solid, poorly soluble in water.

Availability

Silver acetate is sold by various chemical suppliers.

Preparation

Silver acetate can be made by the reaction of glacial acetic acid and silver carbonate, at 45–60 °C. After the reaction has completed, cool the solution to precipitate the silver acetate.

2 CH3CO2H + Ag2CO3 → 2 CH3COOAg + H2O + CO2

Another route involves mixing two concentrated solutions of silver nitrate and sodium acetate. Silver acetate precipitates, while sodium nitrate stays in solution. Filter the poorly soluble silver nitrate, then wash it with cold distilled water, and let it dry.[1] Avoid doing this reaction in strong light.

Projects

Handling

Safety

Silver compounds are harmful and tend to stain. Wear proper protection when handling them.

Storage

In closed plastic or glass containers, away from light and acids.

Disposal

Can be reduced to elemental silver, which can be recycled.
