SUMMARY
The discussion centers on the chemical reaction involving baking soda, vinegar, and toilet paper, which results in a blue color change when subjected to a 9V battery. The blue color is attributed to the oxidation of copper electrodes, producing blue copper ions (Cu2+). Participants suggest that the presence of sodium acetate and other compounds, such as nickel acetate, may also contribute to the color change. The oxidation process at the anode is critical, and the use of different electrode materials is recommended for further experimentation.
