Standard Electrode Potential
As we already discussed that the potential difference between the metal and its solution is known as the electrode potential. If the concentration of the participating species in the electrode reaction is unity and the reaction occurs at 298K and 1 atm pressure, the electrode potential is referred to as Standard Electrode Potential (E0).
How to measure Standard Electrode Potentials?
The standard electrode potential (E0) of hydrogen gas, in the case of the convention, is 0.00 volts. The redox couple is a stronger reducing agent than the H+/H2 couple when the standard electrode potential is negative. On the other hand, a positive standard electrode potential suggests that the redox couple is a weaker reducing agent than the H+/H2 pair.
Redox Reactions and Electrode Processes
Electrode Potential and Standard Electrode Potential are key concepts in the field of electrochemistry which is the branch of chemistry that deals with relationships between electric potential differences and observable chemical change. Electrode Potential is also used extensively in the development of sustainable battery technologies, as all modern-day batteries work on this principle to create voltage for the smooth operations of electronic gadgets. This article deals with the topic of Electrode Potential and Standard Electrode Potential in detail and helps us understand how electricity or potential is produced using chemistry.
