Description

Not only the type of electrode material and the concentration of the electrolyte solutions can have an influence on the performance of the Daniell element and thus of every galvanic cell. In experiment C4.4.4.5, therefore, the influence of the distance between the two electrodes is investigated. The further apart they are, the greater the internal resistance of the galvanic element becomes and the performance decreases. The ions in solution then have to cover a greater distance.
