What does the term 'redox' stand for?

The term 'redox' stands for reduction-oxidation, which refers to chemical reactions that involve the transfer of electrons between two species. In these reactions, one species undergoes reduction, meaning it gains electrons, while another species undergoes oxidation, meaning it loses electrons. The fundamental nature of redox reactions lies in this electron transfer, which is crucial for various processes, including energy production in cells, metal corrosion, and battery operation.

Understanding the concept of redox is essential because it underscores numerous chemical and biological processes. For instance, in biological systems, redox reactions are vital for cellular respiration and photosynthesis. In electrochemistry, redox reactions are the basis for understanding galvanic cells, electrolytic cells, and various applications in energy storage and conversion.
