Applications of Standard Electrode Potentials
The applications of standard electrode potential in various domain is mentioned below:
Battery Technology
Standard electrode potentials are crucial in designing and optimizing electrochemical cells, including batteries. The choice of electrode materials, electrolytes, and cell configurations is guided by the standard electrode potentials to achieve desired performance characteristics such as voltage, capacity, and efficiency.
Corrosion Prevention
Standard electrode potentials gives a key to counteracting corrosion. The execution of sacrificial anode systems is carried out by having metals with the more negative standard electrode potential coupled with the structure which has to be protected. It can then prevent or minimize corrosion.
Electroplating
Electroplating relies on standard electrode potentials to deposit a layer of metal onto a substrate for decorative or functional purposes. By selecting appropriate metal ions with suitable standard electrode potentials, electroplating processes can be tailored to achieve desired coating thickness, uniformity, and adhesion.
Analytical Chemistry
Standard electrode potentials are utilized in various analytical techniques, such as potentiometric titrations and electrochemical sensors. These techniques exploit changes in electrode potential to quantify analytes in solution.
Standard Electrode Potential
Standard electrode potential (EĀ°) is a measure of the tendency of a half-reaction to occur as a reduction at a standard condition. In the context of standard electrode potential, āstandard conditionsā refer to a set of specific conditions under which the potential is measured. It includes standard concentration of all aqueous species to be 1 mol/L, pressure to be 1 atm and temperature to be 25ā or 298K.
