Strong and Weak Acids



The topic of acid-base reactions is a regular component of many chemistry curricula. This topic requires integrated understanding of many areas of introductory chemistry. Many students have considerable difficulties understanding concepts and processes involved in this topic (students often have difficulties to understand the pH scale).

This module offers activities in which acid-base reactions and differences in behaviour of strong and weak acids in solution are analysed. The following activities are available:

  • Data logging - Two laboratory experiments involving the titration of strong and weak acids with a strong base.
  • Modelling - Mathematical models which describe the concentration of [H3O+] and the change of pH during a titration. The simulations help to answer the questions raised in the data-logging activities.
