All reactants that lie above the standard hydrogen electrode in the table are stronger reductants than H⁺.

Question

Quizplus · Accepted Answer

The standard hydrogen electrode (SHE) serves as a reference point (0 volts) in the electrochemical series. Reactants that lie above the SHE in the table have a more negative standard electrode potential, making them stronger reductants than hydrogen. However, the compound "H⁺" as written does not correspond to a recognized chemical species, so the comparison is not meaningful. Generally, the position relative to SHE determines reductant strength, not the comparison to an undefined compound.
