What is the process of reduction associated with?

The process of reduction is fundamentally associated with the gain of electrons by a molecule, atom, or ion. In chemical terms, when a substance undergoes reduction, it becomes more negatively charged because it is accepting electrons, which are negatively charged particles. This process is essential in redox (reduction-oxidation) reactions, where reduction is one half of the reaction that occurs in tandem with oxidation (the loss of electrons).

In the context of electrochemistry, reduction plays a vital role, especially in processes such as electroplating, battery function, and corrosion prevention strategies. Understanding the concept of reduction as gaining electrons helps to clarify many fundamental principles in electrochemistry and corrosion science.
