Which branch of chemistry deals with the transfer of electric charge in chemical reactions?

The branch of chemistry that focuses specifically on the transfer of electric charge during chemical reactions is electrochemistry. This field studies the relationship between electrical energy and chemical changes, which is fundamental in processes such as batteries, fuel cells, and corrosion. Electrochemistry involves understanding how electrons are transferred in redox (reduction-oxidation) reactions and how these processes can be harnessed for practical applications.

Physical chemistry, while it does examine the physical properties of chemical systems and their reactions, does not primarily focus on charge transfer. Organic chemistry concentrates on the structure, properties, and reactions of carbon-containing compounds, while inorganic chemistry deals with non-organic compounds and their behaviors, excluding the specific mechanisms of electron transfer that characterize electrochemistry. This context highlights why electrochemistry is uniquely suited to addressing the study of electric charge transfer in chemical processes.
