Beschreibung:
To measure a pH value, reference electrodes are used. These electrodes output different voltage values depending on the pH value.
The pH value is thus not measured directly, but it must be calculated from the observed voltage.
Notes:
Observe the safety information in the instructions. The materials may be used only as instructed by your teacher or as described in the experimenta-tion instructions. The beverages are not suitable for consumption.
