An Exact Method to Determine the Conductivity of Aqueous Solutions in Acid-Base Titrations

Figure 7

Plots of and as a function of for the titration system stated in Figure 6. (a) The plots of the system’s conductivity and the corrected conductivity are different because of a large dilution during titration. (b) Plots experimental (markers) and estimated through (23) and (3) (solid line) and its first derivative, (segmented line). The thin solid lines are added to emphasize the linear trends in the conductivity curve while the broken lines are ancillary elements to emphasize that the slope changes must coincide for both graphical representations: and .
