On the isohydricity concept-some comments

The isohydricity property, referred to systems composed of acids or bases, is presented. The related isohydricity conditions are formulated for different pairs of solutions. The pH titrations in the system of isohydric solutions are put in context with conductometric titrations. The differences between pK1 values obtained according to both methods are not too significant and the conductometric titration can be perceived, in some instances, as a reasonable alternative to the pH titration.
