Multiple Choice
In addition to redox indicators and starch-iodine complex,the equivalence point for a redox titration can be determined using a Gran plot.Which is NOT true for Gran plots?
A) Gran plots give best results using redox data well before the equivalence point.
B) Gran plots are constructed by plotting the volume titrant added on the x-axis and V10−nE/0.05916 on the y-axis.
C) The plot of V versus V10−nE/0.05916 is a straight line with the x-intercept = equivalence point volume.
D) Constant ionic strength over the course of the titration minimizes error in the equivalence point.
E) Gran plots are more error prone than first derivative and second derivative plots.
