The dissociation constants of nitrophenoxazines in isobutyl methyl ketone (MIBK) were determined and correlated with the HNP values in acetone. Of the derivatives studied, the strongest acid is 1,3,7-trinitrophenoxazine (pK = 19.8), the weakest, 1-nitrophenoxazine (pK > 26). The compounds have no tendency to homo- or heteroconjugation, and were used as indicators in determination of weak acids in MIBK. Some derivatives of malonic acid and of 1,2,4-triazine as well as the intermediates used in their synthesis were determined; their HNP and pK values were established. The shape of the potentiometric titration curves can be of assistance in solving some structure problems.
