A standard solution of iron was made by weighing 0.075 g of Fe(NH4)2(SO4)2 6(H2O) in 250 mL. Aliquots of this standard solution (see below) were transferred to a 100 mL volumetric flask, pH adjusted with citrate, and reacted with hydroquinone and o-phenanthroline and diluted to volume (100 mL). The absorbance was measured in a 1.0-cm cell using a Genesys 20 Spectrophotometer at 508 nm: Aliquot of standard solution Absorbance 1.0 mL 0.079 2.0 mL 0.163 5.0 mL 0.413 10.0 mL...

Please help me balance the equation: ___ Fe(NH4)2(SO4)2 · 6 H2O + ___ H2C2O4 + ___ K2C2O4 + ___ H2O2 → ___ K3Fe1(C2O4)3 * 6 H2O + ___ (NH4)2SO4 + ___ H2SO4 + ___ H2O (Hint given: Remember H2O2, an oxidizing agent, was used in the synthesis, so you’ll need to do a redox balance. Start with just the iron ions, balance the reaction, and then add the full formulas.)
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 su...
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.
