Redox Titration of Ferricyanide to Ferrocyanide with Ascorbic Acid: Illustrating the Nernst Equation and Beer–Lambert Law Tina H. Huang, Gail Salter, Sarah L. Kahn, and Yvonne M. Gindt
In this simple experiment, which illustrates the Nernst equation and BeerLambert law, students monitor the reduction of ferricyanide ion to ferrocyanide electrochemically and spectrophoto-metrically upon titration with ascorbic acid.

Electropolymerized Conducting Polymer as Actuator and Sensor Device: An Undergraduate Electrochemical Laboratory Experiment María T. Cortés and Juan C. Moreno
A trilayer formed by two conducting polymer films sandwiched around an adhesive polymer layer works as actuator and sensor simultaneously. This device can be bent up to 180 and it can be used as a sensing device of physical chemistry parameters such as cell temperature and electrolyte concentration. In this article, it is shown in a didactic way how to electrochemically synthesize ClO4-doped polypyrrole (PPy) films, how to fabricate a trilayer device, and how to evaluate its actuating and sensing capabilities. The required materials are simple and a complicated setup is not necessary.

Teaching pH Measurements with a Student-Assembled Combination Quinhydrone Electrode Fritz Scholz, Tim Steinhardt, Heike Kahlert, Jens R. Pörksen, and Jürgen Behnert
A combination pH electrode that can be assembled by the student is described. It consists of a glass holder and two sensors in the form of rubber stoppers that contain quinhydrone and graphite. The combination electrode is suitable to teach potentiometric measurements, pH measurements, and the interplay of acidbase and redox equilibria. The electrode meets highest safety standards and overcomes the troubles associated with the use of the conventional quinhydrone electrode.

Using Organic Light-Emitting Electrochemical Thin-Film Devices To Teach Materials Science Hannah Sevian, Sean Müller, Hartmut Rudmann, and Michael F. Rubner
Light-emitting thin films provide an excellent opportunity to learn about principles of electrochemistry, spectroscopy, microscopic structure of the solid state, basic circuits, and engineering design. There is currently strong interest in academic and industrial engineering research centering on developing organic light-emitting devices for applications in flat panel displays. In this educational module, designed for high school or introductory undergraduate courses, students learn how to make a ruthenium-based thin-film device. In the process, they learn about the solid-state electrochemistry at work in the film, as well as the electroluminescence that results when current passes through the device.

Just Breathe: The Oxygen Content of Air JCE Editorial Staff
Students estimate the percent oxygen (volume) in air using steel wool in a test tube that is inverted in a beaker of water. Oxygen in the trapped air reacts with iron to form rust, and the water level rises inside the test tube; within 30-45 minutes, the majority of oxygen is consumed.

Student Construction of a Gel-Filled Ag/AgCl Reference Electrode for Use in a Potentiometric Titration James M. Thomas
Instructions for the preparation of a Ag/AgCl "reference"-type electrode that uses a gel-type matrix are given. 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 to determine the percent of iron in Fe(NH4)2(SO4)2 and in Fe2O2 unknowns purchased commercially.

A Closer Look at the Addition of Equations and Reactions Damon Diemente
Chemists occasionally find it convenient or even necessary to express an overall reaction as the sum of two or more component reactions. A close examination, however, reveals that the resemblance between chemical algebraic equations is entirely superficial, and that the real meaning of addition in chemical equations is subtle and varies from case to case. In high-school courses, students are likely to encounter the addition of equations in thermochemistry, in electrochemistry, and in kinetics.
