In the half-equation at the ethanol electrode, which substances are produced?

At the ethanol electrode during an electrochemical reaction, ethanol undergoes oxidation, leading to the production of byproducts. The oxidation process of ethanol involves the removal of hydrogen atoms, converting ethanol into carbon dioxide. Additionally, as ethanol is oxidized, hydrogen ions are released into the solution.

This reaction can be summarized by the half-equation, which typically shows ethanol losing electrons (oxidation) and producing carbon dioxide and hydrogen ions as a result. The generation of carbon dioxide is a key aspect of this process, highlighting the transformation of organic materials into gaseous products during oxidation.

In this context, the choice indicating carbon dioxide and hydrogen ions as the products accurately reflects the fundamental processes occurring at the ethanol electrode during oxidation, distinguishing it from other potential byproducts or reactions that do not take place under these specific conditions.
