BACKGROUND: Synthesis of Potassium Iron (III) Oxalate Hydrate Salt The iron(II) ions from Fe(NH4)2(SO4)2•6H2O will be precipitated as iron(II) oxalate. Fe^2+(aq) + C2O4^2-(aq) --> FeC2O4 (s) The supernatant liquid, containing the ammonium and sulfate ions, as well as excess oxalate ions and oxalic acid will be decanted and discarded. The solid will then be re-dissolved and the iron(II) ions will be oxidized to iron(III) ions by reaction with hydrogen peroxide. 2Fe^2+(aq) + H2O2(aq) --> 2Fe^3+(aq) +2 OH^ - (aq) The...
