electroquímica

Electroquímica is the branch of chemistry that studies how chemical reactions produce electricity or how electrical energy causes chemical changes. It involves processes like batteries, where chemical reactions generate electrical current, and electrolysis, where electricity drives chemical transformations. These reactions typically occur at electrodes—surfaces where oxidation (loss of electrons) and reduction (gain of electrons) happen. Essentially, electrochemistry explains how energy is converted between chemical and electrical forms, playing a vital role in power sources, sensors, corrosion prevention, and various industrial applications.
