Solvent for ferrous oxlate
I am leaching iron oxide using oxalic acid but the compound formed is ferrous oxalte which is also insoluable in water and supposed to report in
filterate.
Is there any solvent by which I can dissolve the ferrous oxalte and separate it from unreacted material ?
thanks

Heat it until it decomposes then react the iron with HCL.

I believe he wants the ferrous oxalate, not end up with Iron Chloride. But I may be wrong. Can you give more details, veerenyadav?

I doubt very much if non-reactive, practical solvents for ferrous sulphate exist.
By oxidising the ferrous oxalate to ferric oxalate in the presence of excess potassium oxalate the water-soluble complex potassium trisoxalato ferrate
(III) is obtained. With strong alkali, Fe(OH)3 can be precipitated from its solutions and the oxalates recovered. But whether that kerfuffle is worth
doing for some iron waste I'm not sure...

Perhaps it would be more soluble in hot water? Wiki lists an abysmal 0.08 g/ 1L solubility at RT. Maybe you should use a Soxhlet extractor, that's
always a fun way to extract sparingly soluble compounds.

Just try oxalic acid, it is known to form soluble complexes with its salts.

Thanks for replies but
Actually, I want to recover ferrous oxalte.
I can get the iron hydrooxides and cloride but than I get it directly reacted with HCl or NaOH.

In the case of iron, only with ferric oxalate.
