Which electrode has a higher electric potential?
Top best answers to the question «Which electrode has a higher electric potential»
- "An electron has a higher potential energy when it is at which electrode in a galvanic cell: Answer: The anode because electrons flow toward the cathode" Okay, so an electron has a higher potential energy at the anode.

In the Zn/Cu system, the valence electrons in zinc have a substantially higher potential energy than the valence electrons in copper because of shielding of the s electrons of zinc by the electrons in filled d orbitals. Hence electrons flow spontaneously from zinc to copper(II) ions, forming zinc(II) ions and metallic copper.
On comparing the values of oxidation potential, the higher oxidation potential is the anode, while the lower oxidation potential is the cathode, It is possible to obtain electric energy from the galvanic cell, where oxidation takes place at Zn electrode and reduction takes place at Cu electrode, where the oxidation potential of Zn is 0.76 volt and the reduction potential of Cu = 0.34 volt.
Now, More electrons have been released at the anode as compared to the cathode. So, we may say that the anode is more able to “push” electrons to the other side because of this gradient of electrons created. That is why, anode has a higher electrode potential. 5.1K views.
Basic physics defines the higher potential end as starting point of energy flow and lower potential as ending point of energy flow. Since current starts from Positive Battery Terminal, it is considered as Higher Potential and ends at Negative Terminal, this is considered as lower potential. Hope I have answered both the parts of your query. Cheers!!!

The electrons involved in these cells will fall from the anode, which has a higher potential to become oxidized to the cathode, which has a lower potential to become oxidized. This is analogous to a rock falling from a cliff in which the rock will fall from a higher potential energy to a lower potential energy.

In electrochemistry, 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. It is defined to have a potential of zero volts. The electrode potential has its origin in the potential difference developed at the interface between the electrode and the electrolyte. It is common, for instance, to speak of the ...
