8. Other pKa determination methods
We now mention a few other methods of pKa determination, briefly outlining their principle.
8.1 Determination by solubility measurements
Let's take the HA/A pair–. Let's think in terms of concentrations. Assume that the HA acid form is only slightly soluble. Let Si be its solubility (mol · L–1) at a given temperature. Si is called the intrinsic solubility. Its total solubility S is given by the expression :
The...
