When acetic acid reacts with silver carbonate, Silver Acetate is formed CH 3 CO 2 Ag or AgC 2 H 3 O 2 . Silver Acetate can also be prepared by adding an acetate ion to aqueous silver nitrate. Physically, it appears as a white or greyish solid with a slightly acidic smell. Silver oxide is formed on heating, resulting in highly reflective, highly conductive silvered polymer films. Silver Acetate is a moderately water-soluble crystalline silver source that decomposes into silver oxide.

In the presence of catalysts such as nickel, palladium, or platinum, silver acetate reacts with molecular hydrogen (H2).
2CH 3 CO 2 Ag + H 2 ⇢ 2Ag + 2CH 3 CO 2 H
Silver acetate decomposes on heating to give acetone, carbon dioxide, oxygen, and silver metal.
2CH 3 CO 2 Ag ⇢ 2Ag + (CH 3 ) 2 CO + CO 2 + (1/2)O 2
Methyl acetate is formed when Silver acetate reacts with methyl bromide. The chemical reaction is shown below.
CH 3 COOAg + CH 3 Br ⇢ CH 3 COOCH 3 + AgBr
