Abstract In the process of teaching titration analysis, a precipitation titration learning software is designed and developed using Python language in order to promote the deep integration of modern information technology and teaching. The software does not need to install and establish complex functions or calculation equations. It is easy to operate for users only by selecting and inputting the corresponding parameters, which can make the precipitation titration curve visualization. In addition, the software can automatically calculate the stoichiometric points, the jumping range, the feasibility of the titration and the titration error. This software is presented in the form of a graphical interface with simple design, convenient operation and rich content. Users can choose built-in or customized titration examples. This software almost contains the important knowledge of the precipitation titration method in the syllabus, which is convenient for teachers to prepare lessons for teaching and students to study independently, cooperating to improve the teaching effect.
