39. When potentiometric titration of a solution of nitrogen-containing compounds with perchloric acid in an ethyl methyl ketone medium, the following titration jumps were obtained on the titration curve: piperidine - 500 mV, methylbenzimidazole - 250 mV, 3,5-dimethylpyrazole - 100 mV, acridine - 150 mV, pyridine - 120 mV. What can be said about the strength of these bases in methyl ethyl ketone? What will the curve look like for the titration of a mixture of piperidine, methylbenzimidazole and 3,5-dimethylpyrazole with perchloric acid?
