Principle

This experiment demonstrates how the characteristics of (chemical) substances can be examined. The students work with substances that they know from their everyday life and they determine the pH value or character (acidic, neutral or alkaline) of various solutions. For this purpose, the pH value of aqueous solutions (e.g. vinegar or common salt) is determined with the aid of a pH test stick.

Benefits

  • Experiment guides are very easy to understand, especially for younger students
  • Associated competences are directly linked to the experiments
  • Curriculum compatible
  • Fit for the future: implementation of tablets possible
