Abstract Ionization of 2- and 3-nitroanilines was studied in HCl-DMF-1,1,2,2-tetrachloro-ethane (TCE) solutions at 25 °C. The ionization capability of the medium and basicity constants pK i of indicators change depending on the ratio of the components. The numerical values of pK i are found to depend on the analytical composition of the DMF-TCE solvent. The solvent effect on pK i is associated with a change in the solvation of the nonionized form of the indicators.
