Re: Fe oxalate (was: pt/pd stops)
Did you make it from the direct reaction Fe(NO3)3 + Oxalic acid powders (Vicente-M. Vizcay Castro instructions in http://home.att.net/~jeffrey.d.mathias/guide/FO_intro.htm) or in nitric acid solution (Gmelin Handbook of Inorganic and Organometallic Chemistry)?Ferric oxalate 26%. Ferric oxalate is homemade via the nitric acid route. It is the nicest I ever tested and keeps forever.
I made it once by the second way, obtaining after some days a huge single crystal of Fe(III) oxalate.
BTW, I don't suggest to make this last way if you have not a fume hood.
