Perform a first-hand investigation to identify the conditions under which a galvanic cell is produced
- A successful galvanic cell requires the following conditions:
- Two electrodes of different metals.
- Two separate solutions, each containing the ions of one of the metals used in the electrodes.
- The electrodes being in contact with their corresponding ions in solution.
- A salt bridge between the two solutions.
- A conducting path between the electrodes, which may or may not have a load.
- The necessity of these conditions can be demonstrated by observing the effect of their removal, one at a time.
