Study Notes
Branch of Chemistry
- Electrochemistry deals with the relationship between electrical potential difference and chemical change.
Electron Transfer in Reactions
- In electrochemical reactions, electrons are transferred through oxidation-reduction (redox) processes where one species loses electrons (oxidation) and another gains them (reduction).
Role of Electrolyte
- The electrolyte, which is usually an ionic substance in a liquid or gel form, conducts electricity by allowing the movement of ions, facilitating the transfer of charge during the reaction.
Electrical Potential Driven Reaction
- An electrochemical reaction driven by an electrical potential difference is termed an electrolysis, where the input of energy causes a chemical change.
Electric Battery and Fuel Cell Function
- Electric batteries and fuel cells produce a potential difference through chemical reactions that release energy, allowing the flow of electrical current as a result of electron movement between the anode and cathode.
