Potentiometric Titrations Accuracy The accuracy of a potentiometric analysis is limited by the measurement error for the cell’s potential. Several factors contribute to this measurement error‚ including the contribution to the potential from interfering ions‚ the finite current drawn through the cell while measuring the potential‚ differences in the analyte’s activity coefficient in the sample and standard solutions‚ and liquid junction potentials. Errors in accuracy due to interfering ions

Determination of Iron by Reaction with Permanganate-A Redox Titration Purpose: The purpose of this experiment was to find the percentage of iron in an unknown iron oxide sample which could be determined through titration with a standard solution of potassium permanganate. Success in this analysis requires careful preparation and attention to detail. Performing this experiment also provides practice at titrations. The overall reaction is: 8H+(aq) + MnO4-(aq) + 5e- Mn2+(aq) + 4H2O Theory:
