Fe(COO)2
Formula: FeC2O4
If you want to separate ferrous oxalate from titanium oxalate, you need to put them in an alkaline solution and introduce heat. They should break apart into their two respective oxolates.
Add ferrous chloride solid to saturated aqueous solution of oxalic acid then to expel the HCl gas then saturated solution is allow to cool the crystals of ferrous oxalate settled down with in few minutes remove the excess liquid and get the dry compound.
For example sodium oxalate has the chemical formula Na2C2O4.
The formula for ferric oxalate is Fe(C2O4)3.
The chemical formula of zinc oxalate is C2O4Zn.
The chemical formula for molybdenum oxalate is Mo(C2O4)2.
Formula of ammonium oxalate monohydrate: (NH4)2C2O4.H2O
The formula for ferrous sulphate is FeSO4.
The chemical formula for Calcium Oxalate is CaC2O4
The chemical formula for manganese II oxalate is MnC2O4.
The formula of iron(III) oxalate is C6Fe2O12.
