Which of the following is TRUE about standard electrode potentials?

Question

Quizplus · Accepted Answer

The electrode potential of the standard hydrogen electrode is defined as exactly zero, by convention. This makes it a reference point for all other electrode potentials.

Answer: B
 Electrons flow spontaneously from an electrode with a more negative electrode potential to an electrode with a more positive electrode potential. This is because the electrons are attracted to the more positive electrode and repelled by the more negative electrode.

Answer: E
 The electrode potential of any half-cell with a greater tendency to undergo reduction (i.e. gain electrons) will be negative relative to the standard hydrogen electrode. This is because the standard hydrogen electrode has a zero potential, and the reduction potential of any other half-cell will be measured relative to this zero point. A negative reduction potential means that the half-cell has a lower tendency to gain electrons, and so will have a more positive oxidation potential.
