How to make silver acetate?

- May 03, 2017 -

Silver acetate can be synthesized by the reaction of acetic acid and silver carbonate at 4560 °C. After allowing cooling to room temperature, the solid product precipitates.

 

2 CH3CO2H + Ag2CO3 2 AgO2CCH3 + H2O + CO2

It can also be precipitated from concentrated aqueous solutions of silver nitrate by treatment with a solution of sodium acetate.

 

The structure of silver acetate consists of 8-membered Ag2O4C2 rings formed by a pair of acetate ligands bridging a pair of silver centers.
