Derivative of titration curve

WebDec 30, 2024 · A titration curve is a plot of the concentration of the analyte at a given point in the experiment (usually pH in an acid-base titration) vs. the volume of the titrant added.This curve tells us whether we are dealing with a weak or strong acid/base for an acid-base titration. The curve around the equivalence point will be relatively steep and … WebThe first derivative of titration curve: The changes in pH value per unit volume of titrant added ( pH/ V) vs volume of titrant added are plotted (Fig. 13-3). The point having a maximum pH/ V value is the equivalence point. Figure 13 …
