What is Ferrous oxalate?

Description

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.

Chemical properties

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

The Uses of Ferrous oxalate

Used as a photographic developer, glass tint, decorative glass colorant, and pigment in plastics, paints, and lacquers.
