Abstract In view of the difficulties in teaching the titration curve of binary weak acid, this paper develops a teaching software with H2C2O4 and Na2C2O4 as examples, which can display the change images of each particle in the titration process. With the auxiliary teaching function of teaching software and the design of problem-driven teaching activities, students can experience the drawing principle of logarithmic straight line and distribution coefficient curve, and discuss the “special points” of binary weak acid titration curve, particle concentration size and exercise verification based on teaching software.
