Titration curve of a diprotic acid with a strong base titrant This would be a strong acid too and the inflection point would be that for water at pH 7. Note that the pKa 1.69 is assuming H X + X X − and is taken at 1/2 of the N a X + O H X − used. Knowing that H X 2 S O X 4 has two protons, the second pKa should be taken at 150% on the plot which would give the correct pKa value of 1.99.
