Oxidation and Reduction HRPObjectivePerform a redox titration on Horseradish Peroxidase to determine the standard potential. ProtocolThe procedure used for the lab comes from Dr. Hartings lab notebook. A total of 5 groups analyzed the cell potential. Group CMJ went first and in the middle of the five runs, the amount of sodium dithionite added to the cell was adjusted. The amounts and concentrations of sodium dithionite added were kept for each group. DataThe class data follows below:
