Technical data

Acidic or basic character of solutions

Article no: P7150104

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
