Isohydric method

Such an approach is, in several aspects, a novelty when compared with ones practiced hitherto. This acid-acid titration has some similarities to titrations made for determination of pK values according to the new, isohydric method suggested by Michalowski and presented in the previous papers. ...

The reliability of the method is illustrated by results taken from the report of Kolthofp and Kameda. It is clear from the table that a 100 55 bromthymol mixture and a 100 10 phenol red mixture are isohydric with pure water. 

In the case also when one studies complex coacervation by means of turbidity measurements (a method which can be employed at smaller colloid concentrations) one arrives at similar results. Compare Fig. 3 and 4, which refer to isohydric series of mixtures of 0.05% sols.
