WebApr 3, 2024 · pKa = − log[Ka] According to this definition, the pKa value for HCl is as follows: pKa ( HCl) = − log107 = − 7 Whereas the pKa for ascorbic acid is: pKa ( ascorbic acid) = − log6 × 10 − 12 = 11.80 As is clear, the smaller the pKa value, the stronger the acid. pKa and pH of Buffer Solution WebFeb 2, 2024 · In general, for titrations of strong acids with strong bases (and vice versa), any indicator with a pK in between about 4.0 and 10.0 will do. For the titration of a weak acid, however, the pH at the equivalence point is greater than 7.0, so an indicator such as phenolphthalein or thymol blue, with pKin > 7.0, should be used.
