Silver oxalate (Ag
2C
2O
4) is a silver salt of oxalic acid 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.[2] It is also a precursor to the production of silver nanoparticles.
It is explosive upon heating around 140 degrees Celsius, shock or friction.

Production
[edit]Silver oxalate is produced by the reaction between silver nitrate and oxalic acid.
