Silver oxalate is a silver salt of oxalic acid with the chemical formula Ag
2C
2O
4. It is sensitive to light, decomposing to metallic silver and carbon dioxide.[3]

Production

Silver oxalate is produced by the reaction between silver nitrate and oxalic acid, or from combining solutions of silver nitrate and sodium oxalate.[3]

Uses

It is commonly employed in experimental petrology to add carbon dioxide (CO
2) to experiments as it will break down to silver (Ag) and carbon dioxide under geologic conditions.[4]

It is also a precursor to the production of silver nanoparticles.

Safety

It is explosive upon heating around 140 °C (284 °F) and the dry material may explode when ground.[5]
