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

Figure 1

Plots obtained during titration of 20.00 mL H₂SO₄ 0.024 M + 430.0 mL deionized water with NaOH 0.2743 M, at 25°C. (a) pH-metric plots: the solid line represents the plot obtained with (10) while the segmented line represents the plot of . (b) Conductometric plot . The markers represent the experimental points obtained and the solid line represents the estimated plot with (11); the segmented line represents the plot , obtained from the fitted model.
