Envíe este artículo por correo electrónico Selection of titration indicators in Analytical Chemistry
Resumen
Analytical chemistry textbooks are focused on plotting titration curves and only the titration error is calculated. They do not focus on selecting indicators for a given titration, a situation that professionals might face at work. Examples on this topic are incomplete and the theory does not cover the necessary material. In this study, examples of indicator selection for acid-base, complexometric, and oxidation-reduction titrations are solved. The theoretical foundations of these exam-ples are shown and some problems are solved. Classical titrations are precise and accurate at high concentrations, do not need calibration, have a high didactic value, and make up many standardized methods.
