Ferrous oxalate

Description

Ferrous oxalate, or iron (II) oxalate, is a chemical compound consisting of one iron (II) ion (Fe²⁺) and one oxalate ion (C₂O₄^2-). 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.

Chemical properties

Pale-yellow, crystalline powder; odorless. Soluble in acids; insoluble in water.

The Uses of Ferrous oxalate

Photographic developer, pigment in glass, plastics, paints.

Reactivity Profile

Inorganic reducing agents, such as Ferrous oxalate, react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive.

Hazard

Toxic. Evolves carbon monoxide on heating.

Health Hazard

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.

Fire Hazard

Special Hazards of Combustion Products: Iron fume or iron oxide fume may form in fire.
