| Abstract: | An experimental procedure on the determination of concentration constants for weak acid or/and weak base were presented by potentiometer titration with pH glass electrode. Relative errors of concentration constants for weak acid and weak base between determining value and reference value are below 5%. Standard deviations of determining value for pK c in different ionic intensity are below 1%. |
