What is the standard electrode potential for the positive electrode in the cell configuration?

The standard electrode potential of the positive electrode in an electrochemical cell indicates the tendency of the electrode to gain electrons, reflecting its ability to function as a cathode in a galvanic (or voltaic) cell. A high positive value, such as 2.91V, signifies a strong oxidizing agent, which effectively pulls electrons towards it.

In the context of standard electrode potentials, a positive value indicates a favorable reduction reaction occurring at that electrode compared to the standard hydrogen electrode, which is assigned a potential of 0.00V. This means the electrode with a potential of 2.91V can easily attract electrons from the other half-cell, making it the reaction site where reduction takes place.

When evaluating other values, -3.04V represents a scenario where the electrode exhibits a strong tendency to lose electrons rather than gain, indicating a poor oxidizing agent. In contrast, 0.00V is a reference potential which does not indicate a strong tendency for reduction, and 3.04V suggests an inconsistency since electrode potentials are typically referenced against the standard hydrogen electrode and are not usually presented with such high values in practical use.

Thus, the recognition of 2.91V as a significant potential aligns well with the
