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.

WebA titration curve is a plot of some solution property versus the amount of added titrant. For acid-base titrations, solution pH is a useful property to monitor because it varies … WebThe pH after the equivalence point on a titration curve for both weak and strong acids gradually increases due to excess strong base. Other features of a weak acid titration curve, but not a strong one, are the buffer region and the half-equivalence point. When a strong base is added, a weak acid produces its conjugate base creating a buffer.
