The aim of this experiment is to show and explain to the students how indicators can be used in analytical chemistry and to familiarise them with the fundamental principles of titration. Futhermore, a special focus is set on indicators and their various colour transition ranges.

During this experiment, the students have to determine the unknown concentration of hydrochloric acid (solution to be analysed) with the aid of several indicators. For this purpose, a known volume of the acid is titrated with a volume of a sodium hydroxide solution of a known concentration (standard solution) until the indicator changes colour. The used volume of the standard solution and its concentration are then used to calculate the concentration of the solution being analysed.

Learning objectives

  • Titration of a strong acid 



  • Experiment literature available for pupils and teachers: Minimum preparation time
  • Simple teaching and efficient learning by using the available interactive experiment literature
