When mixing [Fe(C2O4)]3- with dilute -OH, reddish brown ppt are formed. However, (C2O4)2- is a stronger ligand than -OH, why reddish brown ppt will be formed?作者: a221962 時間: 2013-11-4 11:31 AM
The reaction
Fe(OH)3 (s) <--> Fe3+(aq) + 3 OH-(aq)
is reversible
so where there're Fe3+(aq) + 3 OH-(aq)
there's Fe(OH)3 (s)
