Hydrogen Power: Exploring Electrolysis – Teacher

Summary

Students explore hydrogen as an energy carrier by examining production methods, including the hydrogen color labeling system, and then build and operate a simple electrolytic cell using a 9V battery, graphite electrodes, and tap water. The lab connects chemistry concepts (oxidation, reduction, half-reactions) to real-world hydrogen production trade-offs. Includes a full answer key. Appropriate for high school chemistry, Earth and Environmental Science, or an APES energy unit.
