The two key applications of the electrochemical series are:
- Predicting the spontaneity of redox reactions by comparing the standard electrode potentials of different elements or ions.
- Designing and selecting appropriate materials for galvanic cells and batteries by determining which will act as anode and cathode based on their electrode potentials.
These applications allow understanding of the oxidizing and reducing powers of elements and help in the practical design of electrochemical cells and corrosion prevention.
