Study Notes
Electrochemistry
- Branch of physical chemistry that deals with the relationship between electrical potential difference and identifiable chemical change
- Involves reactions where electrons move via an electronically-conducting phase, typically an external electrical circuit
Electrochemical Reactions
- Driven by an electrical potential difference, as in electrolysis
- Result from a chemical reaction, as in an electric battery or fuel cell
- Electrons are not transferred directly between atoms, ions, or molecules, but via an electronically-conducting circuit
Key Reaction Components
- Electrodes: separated by an ionically conducting and electronically insulating electrolyte (or ionic species in a solution)
- Electronically-conducting phase: allows electrons to move between electrodes
- Ionically conducting and electronically insulating electrolyte: separates electrodes and enables ionic conduction
Test your knowledge of electrochemistry with this quiz covering the relationship between electrical potential difference and chemical change, electron movement, and electrode reactions in an electrolyte.
