Hi.

In my lab we synthesized:
K₃Fe(C₂O₄)₃•3H₂O from:

10g Fe(NH₄)₂(SO₄)₂•6H₂O and
50mL 1M H₂C₂O₄ and
1mL 3M H₂SO₄ and
20mL K₂C₂O₄ (saturated at 40°C) and
40mL 3% H₂O₂ and
20mL C₂H₅OH

And I am supposed to calculate the % yield of the K₃Fe(C₂O₄)₃•3H₂O crystals (ended up with 4.102g) but the saturated potassium oxalate has me thrown off. I'm not sure what saturation means as far as molarity and so I'm not sure exactly how much is in there.

Any help is appreciated, thanks!

If you must figure out the % yield based on potassium oxalate, then you'll simply have to look up what g/L a saturated solution of potassium oxalate.  The question for me is, which reactant should you use to figure out % yield?  It should be the limiting reactant, and I don't know exactly which one that is.

Ah... I feel dumb, the LR is the 10g Fe compound, so nevermind about the whole saturated thingy. Thanks for helping me have this realization though!

You should find data for solubility of K2C2O4 at 40°C before check for a limiting reagent or calculate yield assuming Mohr's salt is a limiting reagent
