Electrochemistry

Electrochemistry is the branch of chemistry concerned with the relationship between electrical potential difference and chemical change.
Electrochemical reactions involve the transfer of electrons from one species to another, resulting in a change in the chemical composition of the reactants.
The outcome of a particular chemical change in electrochemistry depends on the specific reaction and the conditions under which it is carried out. It can involve the production of electricity (e.g., in a battery), the consumption of electricity (e.g., in electrolysis), or the conversion of chemical energy into electrical energy (e.g., in fuel cells).
Electrons move through an external circuit during electrochemical reactions.
Electrodes are separated by an electrolyte in electrochemical reactions. This allows the transfer of ions to balance the charge transfer that occurs during the electron movement.
A chemical reaction driven by an electrical potential difference is called electrolysis. This process uses an external electric current to drive a nonspontaneous chemical reaction.
