This paper describes the basic functions and features of acid-base equilibrium calculations software CurTiPot. Based on the Brönsted-Lowry acid-base theory and the extended education content in chemistry course in university, applications of the three types of calculations, including the pH calculation, the titration simulation and the chemical species distribution, are illustrated. It shows that CurTiPot software is helpful in understanding the effect of each parameter of solution on the pH value of buffer, the titration process and the chemical species distribution, which is beneficial for improving the teaching quality. This software can be used to replace the manual calculation in scientific research, which could improve work efficiency.

Key words: CurTipot Software, Acid-base equilibrium, Acid-base titration, Species distribution
