1) The concentration of H2C2O4 in a solution is determined by titrating it with a 0.1053 M permanganate solution. The balanced net ionic equation for the reaction is: 2MnO4-(aq) + 5H2C2O4(aq) + 6H3O+(aq) -- > 2Mn2+(aq) + 10CO2(g) + 14H2O(l) In one experiment, 24.77 mL of the 0.1053 M permanganate solution is required to react completely with 20.00 mL of theH2C2O4 solution. Calculate the concentration of the H2C2O4 solution. Answer in _______ M 2) A dichromate solution is standardized by...
2) ( ) An acidic potassium dichromate can be used to titrate a solution of iron(II) ions since it reacts according to the following equation: Cr2O72 (aq) +6 Fe* (aq) +14 H30' (aq) - 2 Cr* (aq) + 6 Fe" (aq) + 21 H20 (1) a. What is the oxidizing agent in the above reaction? b. A dichromate stock solution is made by dissolving 2.567 g of K Cr2O, (294.2 g/mol) in a total of 50.0 ml. What is the...
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...
