Abstract:  On the basis of evaluation of Potentiometrie curves the р/с values of new complexanes which form two homologous series of 1,2-diaminoalkane- and l^-diaminoisoalkane-iVjiV^'jiV'-tetraacetic acids, as well as the stability constants of their chelates with Ca2+, Sr2+, Ba2+ and Mg2+ cations were determined. The stability constants of Cd2+ complexes were determined by the „tren" method. Measurements were performed at ionic strength /I= 0.10 (KN03) and at temperature of 20°C. The influence of individual alkyl groups on changes of acid-base and chelating properties was investigated.
