The combination of various half-cells to galvanic cells results in differing direct voltages. Consideration of these differences in voltages leads to the arrangement of the metals in a certain succession to an electrochemical (or electromotive) series.
4 Different half-cells (zinc/zinc sulphate solution, copper/copper sulphate solution, lead/lead nitrate solution and silver/silver nitrate solution) are to be prepared and paired in various combinations to galvanic cells. The direct voltages which are thereby measured are to be used to arrange the metals in a certain succession.
