The concentration of a solution of iron(II) sulfate, FeSO4, can be determined through a redox titration. A 50.00 mL sample of the solution is diluted to 250.00 mL with deionized water. A 25.00 mL aliquot is then pipetted into an Erlenmeyer where it is acidified with sulfuric acid and then titrated with a standard solution of potassium dichromate, K2Cr2O7. The reactants and products of the reaction (unbalanced) are as follows: Cr2O72- (aq) + Fe2+ (aq) + Cr3+ (aq) + Fe3+ (aq) a) Write the balanced half-reactions (be sure to indicate which is the oxidation and which is the reduction half- reaction), as well as the overall balanced redox equation for the reaction between the dichromate ion and iron(II) ion in acidic solution. b) Using the data provided here (and above), calculate the molarity of the original iron sulfate solution. Show your reasoning/calculations.
