| Abstract: | The side reaction coefficient of the coexistence ion in the presence of complexation masking a- gent was evaluated from an exercise in the present paper. The sectional titration discriminant of the mixed metal ions M and N was proposed to act as the discriminant of substitution the analytical concen- tration of coexistence ion N for its equilibrium concentration NI] at the stoichiometric point, and the ac- curate equilibrium concentration ENr] was calculated when the condition was not satisfied. |
