ABSTRACT:
The analytical methods of qualitative and quantitative determination of ions in solutions are very flexible to automation. The process of titration is a recurrent process that can be watched by permanent measurement of a simple property such as mass, current intensity, tension, volume [1-3] or a complex property such as adsorption, heat of reaction [4-6], which need a complex evaluation. The present work is focused on modeling the process of titration and presents a numerical simulation of acid-base titration. Titration parameter selected is the pH. The method permits to observe the titration process and identify the equivalence point of titration.
