A 20.00-mL aqueous solution containing tin(II) ions with a concentration of 0.0850 M is titrated with a standard aqueous solution of cerium(IV) ions having a concentration of 0.1100 M. Write a balanced chemical equation for the titration reaction and then find the volume, in mL, of the titrant that is required to reach the stoichiometric point of the titration. b. If the titration were followed potentiometrically using a platinum electrode and a saturated Ag/AgCl electrode, find the following voltages in...

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.
2Fe^2+(aq) + H2O2(aq) --> 2Fe^3+(aq) +2 OH^ - (aq)
