Abstract
Ionization of 2- and 3-nitroanilines was studied in HCl-DMF-1,1,2,2-te trachloroethane (TCE) solutions at 25 degrees C. The ionization capabi lity of the medium and basicity constants pK(i) of indicators change d epending on tile ratio of tile components. Tile numerical values of pK (i) are round to depend on tile analytical composition of tile DMF-TCE solvent. The solvent effect on pK(i) is associated with a change in t ile solvation of tile nonionized form of the indicators.
