Use an Excel spreadsheet to construct a curve for the titration of 50.00mL of 0.4100MFe(CN)633 with 0.4100MCr2+(E0Fe(CN)63/Fe(CN)64=0.36V and E0Cr3+/Cr2+=0.408V). Calculate potentials after the addition of 10.00,25.00,49.00,49.90,50.00,50.10,51.00, and 60.00mL of the reagent. If necessary, assume that [H+]=1.00M2 throughout. (Use a spreadsheet to complete this question.) a. Enter representative values from your Excel spreadsheet. Potential after the addition of 10.00mL of the reagent =V Potential after the addition of 49.00mL of the reagent =V Potential after the addition of 50.00mL of the reagent =V Potential after the addition of 51.00mL of the reagent =V b. In your Excel document, construct the titration curve. Which of the following best matches your plot
