Ferrous oxalate, or iron (II) oxalate, is a chemical compound consisting of one iron (II) ion (Fe2+) and one oxalate ion (C2O42-). It has the chemical formula FeC2O4.
Iron(II) oxalate is more commonly encountered as the dihydrate, FeC2O4·2H2O . Its crystal structure consists of chains of oxalatebridged iron atoms, capped by water molecules.
When heated, it dehydrates and decomposes into carbon dioxide, carbon monoxide, iron oxides and pyrophoric black iron.
Pale-yellow, crystalline powder; odorless. Soluble in acids; insoluble in water.
Photographic developer, pigment in glass, plastics, paints.
Used as a photographic developer, glass tint, decorative glass colorant, and pigment in plastics, paints, and lacquers.
Odorless yellow solid. Insoluble in water and denser in water. Sinks in water.
Inorganic reducing agents, such as Ferrous oxalate, react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive.
Toxic. Evolves carbon monoxide on heating.
Inhalation of dust may cause irritation of nose and throat. Ingestion causes burning pain in throat and stomach; mucous membranes turn white; can also cause vomiting, weak pulse, collapse, and death. Dust irritates eyes and may irritate skin on prolonged contact.
Special Hazards of Combustion Products: Iron fume or iron oxide fume may form in fire.
