Electrode Potential is developed when a metal is dipped into:
Correct answer: C. In its own ions
- A. An acid
- B. A base
- C. In its own ions
- D. Water
Explanation
A) An acid, B) A base, and D) Water are all electrolytes that can cause the development of electrode potential. An acid or a base can donate or accept protons, respectively, which can result in the formation of an electric potential. Water can also be ionized, resulting in the formation of hydrogen or hydroxide ions, which can participate in electrochemical reactions with the metal.Option C: Electrode potential for any given electrode is the voltage or potential difference of a cell assembled from a standard hydrogen electrode and the given electrode with the potential that is being defined. It is the resultant potential difference between a point on the electrode surface and the point in the bulk of the electrolyte, due to the transfer of charged particles as well as the adsorption of some polar molecules.

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.
