Electrochemistry is a branch of chemistry that studies the relationships between electricity and chemical reactions. It involves the transfer of electrons from one chemical species to another and the study of the resulting electrical energy.

Electrochemistry’s scope includes studying batteries, fuel cells, corrosion, electroplating, and electrosynthesis. It also consists of measuring potential differences, conductivity, and other electrochemical properties and developing new technologies for energy storage and conversion. Electrochemistry is crucial in various energy, electronics, and materials science industries.
