Conclusions
-
1.
The relative concentrations of the unprotonated and protonated forms of 2-nitroaniline have been determined together with its solubility and the activity coefficients of the protonated form in aqueous solutions of p-xylenesul.fonic acid at 25‡C.
-
2.
Using the example of p-xylenesulfonic acid a method has been developed for the determination of the degree of dissociation of aryl sulfonic acids in concentrated aqueous solutions.
