Description

There are noble and base metals. This property depends on the potential of the half-cell of a metal. In experiment C4.4.3.1, voltage measurements on combinations of different metals are used to create an electromotive series of the metals. In so doing, the noblest or basest half-cell can serve as reference point.

The experiment can be carried out in two variants: With the demonstration unit for electrochemistry or using CASSY and a salt bridge.
