Student Construction of a Gel-Filled Ag/AgCl Reference Electrode for Use in a Potentiometric Titration

Abstract
Electrochemistry can be one of the more difficult subjects in chemistry, especially for high school students. Tools are needed to help illustrate the practical use of the Nernst equation, half-cell voltages, redox reactions, etc. Instructions for the preparation of a Ag/AgCl "reference"-type electrode that uses a gel-type matrix are given. The construction steps for the reference electrode have been used successfully by our students to construct their own electrodes. In addition, construction steps are provided for a very sturdy Pt-nichrome "inert" electrode, which can be used many times. Together, these two electrodes, along with a multivoltmeter, have been used successfully by our students to determine the percent of iron in Fe(NH4)2(SO4)2 and in Fe2O2 unknowns purchased commercially.
