Potentiometric acid–base titration is introduced as a method to evaluate pK_a values (Brønsted acidity) of protons present in the nodes of water stable Zr₆- and Hf₆-based metal–organic frameworks (MOFs), including UiO-type MOFs, NU-1000, and MOF-808. pK_a values were determined for the three typical types of protons present in these MOFs: μ₃-OH, M–OH₂, and M–OH (M = Zr, Hf). In addition, the data was used to quantify defect sites resulting from either a surfeit or shortage of linkers in the MOFs and to provide information about the true proton topology of each material.
