Micro-scale Electrochemical Cells – Voltaic and Electrolytic

Targets Grades: 10-14
Accommodates 24 Students Working in Groups of 2

Analyze oxidation-reduction (redox) reactions and become familiar with the activity series of metals and its importance in predicting the products of replacement reactions. Students test both Voltaic and Electrolytic cells, and predict and measure cell voltages. Lessons include learning to separate oxidation-reduction (redox) reactions into half reactions, as well as identifying both anode and cathode activity. Minimal prep time required. State of the Art instructor’s manual features background material, easy to follow stepwise protocols, assessment questions, sample data, modeled calculations, and an answer key. Additional equipment required: a DC voltmeter, glassware. Meets AP Science Practices 3 & 7.
