Abstract:

The basic functions and features of Visual MINTEQ, a software for chemical equilibrium modeling, are presented in this paper. Some examples were given to illustrate the usage and application of this program in college chemistry teaching, including pH calculation of buffer solution, acid-base titration simulation, chemical species distribution curve plotting and precipitation-dissolution equilibrium prediction. It was found that the application of Visual MINTEQ software not only enriches the form of classroom teaching, but also improves the students' understanding and mastery of relevant theoretical knowledge, thus establishing a scientific and efficient research method for students' future studying career.

Key words: College chemistry teaching, Visual MINTEQ software, High-efficient class
