Abstract: The H+-alanine system has been studied by the potentiometric method at 25°C in 1.0 M water-methanol solution of NaClO4 UP to methanol mole fraction x(CH3OH) = 0.5.The values of protonation constants log Kn were obtained after experimental data evaluation of the function E = f(V) with the assistance of purpose-made computer programs KALIBR.SKE and AC.BAZ, improved With MAGEC and ESAB2M programs.
