| Abstract: | This paper tries to derive the calculation formulas of pMep and pMsp in compleximetry in theexistence of by - reaction of metalion. A new method is presented in which the concetration of metalion inindicator discoloration point and stoichimetry point are standardized according to its concentration in free statawith the help of constant of look - up table and distribution mefficient. This method make the calcucationformula and its derivation of two points vnited and it is convenient for the study and exchange of researches. |
