Principle

The aim of this experiment is to show and explain to the students how indicators can be used in analytical chemistry. Furthermore, the students will receive a brief introduction to the concept of acid strength. During this experiment, the students examine acids and learn that an indicator shows different colour shades due to the individual strength of an acid.

The experiment is meant to give a first introduction to the topic ’acid strength and indicators’, therefore the students do not need prior knowledge.
