Determination of the Fundamental Electronic Charge via the Electrolysis of Water

The allure of universal physical constants is unmistakable. Membership in this set is reserved for only the most fundamental data in science. To the novice student, these entities often appear more metaphysical than physical; experimentally inaccessible abstractions, frequently confined by orders of magnitude to either the realm of the quantum (e.g. the electronic charge and Planck's constant) or the cosmological (e.g., the speed of light and the universal gravitational constant). It was the intention, therefore, of the AP Chemistry class at our school to demystify one small component of the scientific data bank by designing and executing an experiment sensitive enough to determine, within acceptable accuracy, the value of one of nature's theoretical building blocks, and simple enough to be conducted in a typical secondary school laboratory. The electronic charge was selected because of its ubiquitous application in chemistry and the elegance of the experimental system.
