Dichromate reacts with aqueous iron (II) ion in acidic solution according to the balanced equation: Cr2O72-(aq) + 6 Fe2+ (aq) + 14 H+ (aq) 2 Cr3+(aq) + 6 Fe3+ (aq) + 7 H2O (l) A volume of 18.72 mL of 15.00 M K2Cr2O7 solution was required to titrate a sample of FeSO4 to the endpoint. What was the mass of iron in the sample? How can the balanced net ionic equation help in your determination? Why arent K+ ans SO2-4 found in the balanced equation? Solve and list the steps to the problem.
