In this article, the reactions for acid-base, complexometric, redox and precipitate titrations can be generalized as M + L = N. Accordingly, their titration curve functions can be expressed as two mathematical models. MATLAB was used to analyze the titration curve models. The changing side reaction coefficients in titration process were calculated by a simple iteration method. Finally, the exact titration curves were plotted using this facile method.
