Silver oxalate is a silver salt of oxalic acid with the chemical formula Ag2C2O4. 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 (CO2) to experiments as it will break down to silver (Ag) and carbon dioxide under geologic conditions.[4][clarification needed]
Safety
It is explosive upon heating around 140 °C (284 °F) and the dry material may explode when ground.[5]
