Abstract
Electrochemistry represents a powerful sustainable method for chemical synthesis; however, its widespread application is limited due to the lack of exposure and appropriate basic training of synthetic chemists and engineers in electrochemistry and electrochemical engineering. The introduction of diverse laboratory practices to the current curricula will improve the understanding of electrochemistry and the theory behind its various applications. Here, we suggest an efficient laboratory experiment on the electrochemical reduction of CO2 to CO using inexpensive and readily available materials, such as metal wires, plastic vessels, batteries, and a hand-held CO detector. Students learn to assemble a divided electrochemical cell and perform important electrochemical reactions, such as electrochemical CO2 reduction and hydrogen evolution reaction. In this experiment, students analyze the rates of CO production under different electrolysis conditions and learn to understand the effects of operating parameters (applied potential, electrolyte concentration, and nature of the electrode) on the outcome of the reaction. This new comprehensive laboratory experiment is designed for students to better understand basic principles of electrochemistry and is suitable for undergraduate students.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
