Abstract

Acid-base titrations are connected with aliquots, indicators, titration curves, equivalence point and end point. Understanding the use of titration curves as well as the end point of a volumetry might prove difficult for students Information on indicators and their colors is widely. The aim of this practice is to make students understand these concepts through the experimental calculation of titration curves between different acids and bases. Eventually, students will learn which indicator is the right one for a specific titration.
