Derivative of titration curve

WebUsing the same spreadsheet from the prelab, tabulate the set of titration data you obtained. Calculate the first and second derivatives. Plot pH vs. mL of NaOH solution added, the first derivative plot and the second derivative plot. The equivalence point is found at the volume corresponding to the x-intercept of the second derivative curve. WebSep 14, 2024 · pH relates to pKa in the equation pH = pKa + log[A −] [HA] for any point on the titration curve except at the midpoint. At the midpoint pH = pKa. The acid dissociation constant of the first proton is the largest out of the successive protons. molH2SO3 = Molarity ∗ Volume = 0.10M ∗ 0.07L = 0.007.
