Abstract:

This paper introduces a computer-aided instruction program package for teaching of acid-base titration and complexometric titration. The core parts of the package were programmed using C++ based on general expressions for acid-base titration and complexometric titration of arbitrary mixtures. The parameter file was designed to conduct operations of the software package. Users only need to write the parameter file according to a rule and then to calculate the titration curves of acid-base titration and complexometric titration of complicated system. A graphic user interface was developed to make it easy to implement the package. The package is helpful for the teaching of the theories of acid-base titration and complexometric titration.

Key words: Acid-base titration, Complexometric, Computer-aided instruction package, Graphical user interface, Parameter file
