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. [3]

Contents

Production

Silver oxalate is produced by the reaction between silver nitrate and oxalic acid.
