In volumetric analysis, error of titration determines the reliability of the analysis method. According to the proton balance equation, the precise expressions of the end point error can be derived. The expressions were calculated using the concentration of the substance at the beginning of the titration rather than the end point. The expressions were calculated with the pH at the end point of titration, and not need to calculate the pH at stoichiometric point. The expressions are universal, which can effectively reduce the difficulty of learning and memory, and improve the accuracy of the calculation results.
