More Fun With Oxalic Acid: Synthesis of Sodium trioxalatoferrate(III) monohydrate
As always, you can view this experiment and many others at http://www.backyardchem.com
I decided to indulge in some coordination chemistry today! The oxalate ion is a strong ligand and bidentate to boot so it makes for some nice colorful salts when combined with various transition metals. I was reading about oxalic acid in a 19th century encyclopedia and came across a large section which was erroneously labeled as oxalate "double salts" (as opposed to "complex"). I spotted that oxalate ions coordinate with ferric ions to form emerald green salts. This sounded pretty cool and after some more research I had myself an experiment!
