| Abstract: | In this paper, the curvilinear equation of the complexometric back titration has been derived, the complexometric back titration curve has been drawn and the pN break has been calculated. With the quality of the hyperbolic sime function, the calculating error formula which contains the maximum sharpness index for the complexometric back titration has been proposed. Therefore, the formula for calculating the pN break range of the complexometric back titration has been got. |
