Description
Ferrous oxalate, also known as iron (II) oxalate, is a chemical compound with the chemical formula FeC2O4. It is more commonly found as the dihydrate, FeC2O4·2H2O, and consists of one iron (II) ion (Fe2+) and one oxalate ion (C2O42-). Ferrous oxalate is an odorless, pale-yellow, crystalline powder that is soluble in acids but insoluble in water. It has a crystal structure made up of chains of oxalate-bridged iron atoms, capped by water molecules. Upon heating, it dehydrates and decomposes into carbon dioxide, carbon monoxide, iron oxides, and pyrophoric black iron.
Uses

Check Digit Verification of cas no
The CAS Registry Mumber 516-03-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 516-03:
(5*5)+(4*1)+(3*6)+(2*0)+(1*3)=50
50 % 10 = 0
So 516-03-0 is a valid CAS Registry Number.

Studies on solid state redox reaction of iron(III) oxalate by gas chromatography
Jinhua, Yuan,Xinquan, Xin,Anbang, Dai,Yuchang, Chang
, p. 51 - 60 (2008/10/08)
The solid state redox reaction of iron (III) oxalate with sodium nitrate and tin(II) chloride was investigated in hydrogen atmosphere and helium atmosphere by use of a non-isothermal technique. The evolved gases (EG) formed during the reaction were directly detected by gas chromatography, and the solid products were also identified by XRD, Moessbauer spectra and IR. The results show that the solid state redox reaction can go to completion because electron transfer is much easier than mass diffusion along the boundaries of the reactant. The releasing of crystal and coordination water during the redox reaction also facilitates completion of the reaction. The mechanism of the solid state reaction is also discussed.
