Calculate the volume in milliliters of a .35 mol/L iron(III) bromide solution that contains 75 mmol of iron(III) bromide . Round your answer to 2 significant digits.
A solution of iron (II) sulfate was prepared by dissolving 10.00g of FeSO4-7H20 (FW= 277.9) in water and diluting up to a total volume of 250 ml. The solution was left to stand, exposed to air, and some of the iron (II) ions became oxidized to Iron (III) ions. a 25.0 ml sample of this partially oxidized solution required 23.70 ml of 0.0100M potassium dichromate K2Cr2O7 solution for complete reaction in the presence of dilute sulfuric acid. Calculate the percentage...
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)

Iron thiocyanate (FeSCN2+) is a complex ion that appears orange-red in solution. Iron(III) (Fe3+) and thiocyanate (SCN-) are both colorless in solution. FeSCN2+ (aq) --(equilibrium)-- Fe3+ (aq) + SCN- (aq) a) If you add Fe(NO3)3 to a solution of these ions at equilibrium, in which direction will the reaction run to reach a new equilibrium? b) Silver ions react with thiocyanate ions to form a white precipitate. If you add silver ions to a solution of these ions at equilibrium,...
