Overview
Silver oxalate is a chemical compound of silver. It is used in experimental petrology to add carbon dioxide to experiments. Silver is a metallic element with the chemical symbol Ag and atomic number 47. It occurs naturally in its pure, free form, as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. (L808, L809, L824)

Toxicology
Health Effects
Silver itself is not toxic to humans, but most silver salts are. In large doses, silver and compounds containing it can be absorbed into the circulatory system and become deposited in various body tissues, leading to argyria, which results in a blue-grayish pigmentation of the skin, eyes, and mucous membranes. Argyria is rare, and although, so far as known, this condition does not otherwise harm a person's health, it is disfiguring and usually permanent. Mild forms of argyria are sometimes mistaken for cyanosis. (L809)
Exposure RoutesOral (L808) ; inhalation (L808) ; dermal (L808)
Toxicity Summary
Metallic silver is oxidized and may deposit in the tissues, causing arygria. The silver ion is known to inhibit glutathione peroxidase and NA+,K+-ATPase activity, disrupting selenium-catalyzed sulfhydryl oxidation-reduction reactions and intracellular ion concentrations, respectively. Silver nanoparticles are believed to disrupt the mitochondrial respiratory chain, causing oxidative stress, reduced ATP synthesis, and DNA damage. (L808, A243, A244, A245, A246)
Chemistry & industry
Pharmacology
Metabolism/Metabolites
Silver and its compounds can be absorbed via inhalation, while silver compounds can also be absorbed orally and dermally. It distributes throughout the body in the blood, particularily to the liver. Insoluble silver salts are transformed into soluble silver sulfide albuminates, bind to amino or carboxyl groups in RNA, DNA, and proteins, or are reduced to metallic silver by ascorbic acid or catecholamines. Metallic silver is oxidized and may deposit in the tissues, causing arygria. Silver is eliminated primarily in the faeces. (L808)
Uses & manufacturing
UsesSilver oxalate is used in experimental petrology to add carbon dioxide to experiments. (L824)
Applications
DescriptionSilver oxalate (Ag2C2O4) is commonly employed in experimental petrology to add carbon dioxide (CO2) to experiments as it will break down to silver (Ag) and the carbon dioxide under geologic conditions . It is explosive upon heating , shock or friction .
UsesExptl photographic emulsion (low sensitivity).
