Abstract: An application of the potentiometric pH measurements of a dibasic acid in the presence of an abundance of the metallic ions for a statistical anal. of calcns. of the equil. const. was described. By applying the approxn. value for the metallic ion concn.: [Me²⁺] = 1/2 (2c_Me - c_A), (where c_Me is the concn. of the metal and c_A the conc n. of the ligand) it was detd. that there is a need for at least a 6-fold abundance of the metal ions for the correct calcn. of the equil. const. The evaluation of the calcn. in the case of the chem. equil. with a weak interaction is not possible because the assocn. const. is <10.
