Electrochemistry is a discipline within physical chemistry that concerns itself with examining the correlation between electricity as a quantifiable and measurable phenomenon, and chemical transformation. This field includes various aspects, among which redox reactions occupy a significant domain. These reactions entail electron transfer between atoms or molecules. Electrochemistry further elucidates comprehensive reactions wherein individual redox processes are linked through an external electric circuit and electrolyte intervention. Additionally, it encompasses the task of redox reaction equilibrium adjustment. This textbook attempts to understand the discipline of electrochemistry, and how its concepts have practical applications. While understanding the long-term perspectives of the topics, the book makes an effort in highlighting their impact as a modern tool for the growth of the discipline. For someone with an interest and eye for detail, this book covers the most significant topics in the field of electrochemistry.
