The cathode has the reduction potential:
Correct answer: B. More than the anode
- A. Less than the anode
- B. More than the anode
- C. Same as that of anode
- D. Zero
Explanation
In electrochemistry, the electrode potential is the electromotive force of a galvanic cell built from a standard reference electrode and another electrode to be characterized. By convention, the reference electrode is the standard hydrogen electrode (SHE). It is defined to have a potential of zero volts. In the electrochemical series, the elements above Hydrogen always act as anodes having less(negative) reduction potential because oxidation occurs at them, and they have the tendency to lose electrons. On the other hand, the elements below hydrogen act as cathodes, and reduction occurs at them because they have more( positive) reduction potential than anodes.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
