How to Make Iron(II) Oxalate
Iron(II) Oxalate can be produced using a water-soluble Iron salt and Oxalic acid. Iron Oxalate has a low solubility so it may be easily precipitated by mixing solutions of Fe+2 (aq) and Oxalic acid, H2C2O4.
Solutions of Iron salts such as Iron(II) Sulfate, FeSO4, and Iron(II) Chloride, FeCl2, would work well for preparation of Iron(II) Oxalate. Simply mix the Fe+2 (aq) and Oxalic acid solutions and yellow precipitate should form.
Ignoring the spectator ions, the reaction proceeds as follows,
Once the precipitation is complete, one can filter out and wash the Iron(II) Oxalate, then allow it to dry before crushing it into a powder.
