|---|---|---|---|---|---|
| anode | The electrode at which oxidation occurs during an electrochemical reaction; the electrode that attracts anions in electrolytic cells and repels electrons in voltaic cells.
🗑
|
||||
| battery | One or more voltaic cells arranged to produce electricity.
🗑
|
||||
| cathode | The electrode at which reduction occurs during an electrochemical reaction; the electrode that attracts cations in electrolytic cells and attracts electrons in voltaic cells.
🗑
|
||||
| electrochemical cell | An apparatus consisting of two electrical contacts (electrodes ) that are immersed in an electrolyte solution and joined by a wire.
🗑
|
||||
| electrochemistry | The field of chemistry that involves redox reactions and electricity; the interactions between chemical and electrical phenomena.
🗑
|
||||
| electrode | A conductor of electricity that allows a current to enter or leave an electrolytic cell (or other apparatus).
🗑
|
||||
| electrolysis | A process that uses electricity to force an otherwise nonspontaneous chemical reaction to occur in an electrochemical cell; the separation of a compound into simpler substances by an electrical current.
🗑
|
||||
| electrolyte | A substance that releases ions and conducts electricity when it dissolves in water.
🗑
|
||||
| electrolytic cell | A type of electrochemical cell that uses electricity to produce a chemical reaction.
🗑
|
||||
| electroplating | An electrochemical process in which metallic ions of a usually more expensive metal coat a cheaper metal using an electrical current.
🗑
|
||||
| fuel cell | A class of highly efficient batteries that operate with a continuous supply of reactants for fuel from an external source from which the products are continually removed.
🗑
|
||||
| nonelectrolyte | A substance that will not conduct electricity when melted or dissolved because it does not release ions.
🗑
|
||||
| oxidation | A chemical reaction in which an atom's electrons are lost and its oxidation number increases.
🗑
|
||||
| oxidation-reduction reaction | Any chemical reaction in which electrons transfer or shift; also called a redox reaction. The shift of electrons is shown by changes in oxidation numbers.
🗑
|
||||
| oxidizing agent | The atom or ion that receives electrons during a redox reaction; the substance that causes other substances to be oxidized; the substance that is reduced.
🗑
|
||||
| reducing agent | An atom or ion that donates electrons during a redox reaction; the substance that causes other substances to be reduced; the substance that is oxidized.
🗑
|
||||
| reduction | A chemical process in which an atom gains electrons and decreases its oxidation number.
🗑
|
||||
| salt bridge | A tube of electrolytic gel that connects the two half-cells of a voltaic cell and allows the flow of ions.
🗑
|
||||
| voltaic cell | A type of electrochemical cell that uses a spontaneous redox reaction to produce electricity.
🗑
