17.3: ACID-BASE TITRATIONS - CHEMISTRY LIBRETEXTS
WEB Sep 8, 2020 Plots of acid–base titrations generate titration curves that can be used to calculate the pH, the pOH, the pKa, and the pKb of the system. The shape of a titration curve, a plot of pH versus the amount of acid or base added, provides important information about what is occurring in solution during a titration.

FINDING KA VALUES - SAVE MY EXAMS
WEB Analysis. After the addition of the second portion of acid, the solution is effectively a half-neutralised sample of acid. This is the half-equivalence point at which the Ka = [H +] By measuring the pH at that point you can convert it to [H +] and hence find the Ka of the acid. pH = 4.75. [H +] = 10 -pH = 1.8 x 10 -5 mol dm -3.
