University Chemistry: Galvanic Cell Experiment, Results, and Analysis

This report details an experiment on galvanic cells, focusing on measuring cell potential between different metal electrodes (zinc, copper, and lead) in various electrolyte solutions. The experiment involved setting up voltaic cells, using a voltmeter to measure the voltage produced, and comparing these measured values to theoretical values. The report includes a theoretical review of electrochemistry and galvanic cells, describing the components such as electrodes, electrolytes, and salt bridges, and explaining the redox reactions occurring within the cells. The methodology section outlines the materials and procedures used, including the preparation of the electrodes and the setup of the different cell combinations. The results section presents diagrams of the cell setups, overall redox reactions, and a table comparing measured and theoretical cell voltages. The discussion analyzes the results, noting the electric energy production, the slight differences between measured and theoretical voltages, and the potential causes for these discrepancies, such as contaminations. The report concludes that the voltmeter readings were greater than 0, meaning the redox reactions were spontaneous and that the cells were able to conduct electricity, in accordance with the basic principles of a modern battery. The report also includes references to relevant literature.
