Description

The Daniell element is the enhancement of the Volta element. As a novelty, the electrodes were put into their metal salt solutions instead of acid. This way, the current draw was more constant. In this experiment the students develop the structure of the Daniell element. They then show a current flow between the copper and zinc electrodes by connecting a motor in series with the cell. And finally, the cell is examined quantitatively, with the students measuring the cell voltage with the Mobile-CASSY.
